A change in temperature even by a degree can have a serious impact on industrial products, biological devices, automotive products, and electronics.
Temperature testing for certain products is vital particularly in the aviation industry. It is vital to calibrate a climatic chamber regularly.
This guideline will explore several advantages of calibration, we’re going to analyze:
how the calibration should be done
the frequency of the calibration
factors to consider in choosing a calibration lab
parameters to be considered in the calibration
What the Advantages of Calibrate a Environmental Chamber?
Overtime, the calibration of an environmental chamber will change, just like expected of every other measuring device. The only way to maintain its accuracy and enjoy the full benefit is by constant calibration. Some of the benefits of calibrate a climatic chamber:
Precision Frequent calibration helps to maintain the accuracy of environmental chambers. So can help to eliminate the risk and potential harm that may result from incorrect measurements.
Consistency If a test instrument isn’t right calibrated, it can display inconsistent readings on a device. This makes it difficult to arrive at a conclusion.
Reliability If the calibration of it is not reliable, the results obtained will also not be reliable.
Adherence Calibrated instrument ensures that an instrument is in compliance with industrials and government standards and can be safely used.
Traceability Each time an environmental chamber is calibrated, paper documents are left behind. This will help in tracking the drift of this instruments as well as help in creating a proper calibration interval.
The Frequency of calibrate a Climatic chamber
The main aim of calibrating is to ensure accuracy and reliability of your equipment. Constant use of measuring instruments exposes them to wear which affects their performance.
To maintain the overall efficiency of an environment chamber, calibration needs to be done as frequently as possible. The frequency of calibration of an environment chamber will depend on the following factors:
Manufacturer recommendation Manufacturers of environmental chambers usually provide information on when and how the instrument should be calibrated. This can provide the basis for calibration but other factors needs to be considered to develop the right frequency:
Before or After a Large Project It is vital to ensure that an environmental chamber is working optimally before starting a big project. Also, that has been used for major projects for an extensive period should be calibrated. This is because frequent heavy use can affect accuracy and performance.
Duration and Amount of Use Ideally, the duration and amount of usage should determine the recalibration of an environmental chamber. This means recalibration should be personalize and vary from equipment owner to another.
Equipment Trauma Equipment trauma is almost unavoidable and the most common with environmental chamber. It’s internal overload usually resulting from high volume of use. Once there is an overload, it is important to recalibrate it before further use.
All the aforementioned criteria should be put into consideration when developing the calibration schedule. It is vital to maintain the accuracy of test instruments because it can compromise safety of devices. In the long run, calibration failure is more costly compared to regular calibration.
When looking for a calibration provider ensure they offer all-in-one service. For quality calibration, it is important to include the following items in calibration;
Accurate Measurement Testing The aim of calibrating is for guaranteed accuracy and reliable outcome. When choosing a provider for your calibration make sure they have accurate measurement testing.
Uncertainty Ratio Measurement Your selected provider should be able to evaluate the measurement uncertainty ratio of your environmental chamber. The knowledge of the uncertainty ration of your environmental chamber is important for calculating the accuracy of your measurements. You will also be able to determine change in performance of your environmental chamber.
Traceability Measurement and Calibration Traceability is key for reliable calibration but is mostly taken for granted. When calibrations and measurements are traceable, they can be traced back to national standards for highest quality.
Calibration Certificate A quality calibration service provider will give you a calibration certificate. This document has calibration information and serves as a proof that your equipment is properly calibrated.
Choosing a calibration lab Competence and compliance to highest standards should be your priority when looking for a lab for calibration of your environmental chamber. The following guidelines will help you in choosing a provider.
Accredited Calibrator VS Non-Accredited Calibrator
Both accredited and non-accredited labs can provide calibration services. However, it is important to understand what accreditation means. A respected calibration lab is accredited when it has passed the criteria, which include lab environment, personnel, and traceability. Choosing an accredited lab guarantees the correctness of the calibration service you receive.
Advantages of Choosing Accredited Lab
Confidence in calibration outcome
Technically competent staff
Supervised lab environment
Required measurement uncertainty.
Accredited calibration labs are required to meet highest industrial standard, ISO/IEC 17025
When you think of great people throughout history, who comes to mind?
Most people would think of Albert Einstein, Mother Theresa, Charles Darwin, or Nelson Mandela. Those are great choices, but we’re going to pick one person that we believe beats them all. We pick Norman Borlaug.
You might not know who Norman Borlaug is, and that’s a shame. Mr. Borlaug, using agricultural research, saved a billion lives.
Dr. Borlaug produced a high-yield and disease-resistant strain of Mexican wheat that helped avert a global food crisis in the 1950s and ’60s. His example led to the development of new agricultural research tools, including the plant growth chamber.
What Is A Plant Growth Chamber?
Growth chambers allow researchers to control the environmental conditions when studying plants. Researchers, biologist, and other professionals can control humidity, temperature, light, and other factors.
Growing chambers help plant pathologists fight disease and geneticists develop sturdier food crops. They provide indispensable data for seed germination that the next Norman Borlaug will use to fight off the future food crises.
How do plant growth chambers achieve this? Let’s look at how they benefit agricultural research.
Reproducibility is one of the fundamental elements of experimental science.
A study’s reproducibility is the ability for other researchers to duplicate experiments. This allows others to either confirm or falsify the original study.
Growth chambers do this by allowing researchers to set certain variables during their test. Another researcher can then match these variables to determine whether the same result occurs.
Without growth chambers, there could be variation in other factors that are outside of a team’s control. Small factors, such as an additional few moments of sunlight a day or air composition can cause dramatic variations in results.
Environmental growth chambers ensure equal factors during the verification process. Of course, this relies on the previous team’s record keeping. If there aren’t proper records, the second study will falsify the data and can then work on a solution.
Let’s say that the second study does falsify the original study. If they choose too, they can make adjustments to the factors presented in the first study to see if they can reach similar results. Other researchers can then attempt to reproduce these results and validate the new study.
Researchers can also improve the results from the first study due to the variability provided by plant growth chambers. If the first study shows a 3% improved yield, the second group might make an adjustment that improves yield by 5%.
This research could lead to other breakthroughs, improving access to food for people in non-ideal growing areas.
Testing For Less Than Ideal Growing Regions
One of the largest concerns for agricultural scientists is the lack of farmable land. Many countries across the world face shortages in farmland in the near future. This problem, along with a lack of skilled farm labor, climate change, and a booming worldwide population points to an impending food crisis.
In the UK, it’s expected that there will be a shortage of farms by 2030. In Africa and other parts of the world, the problem isn’t a lack of land, but a lack of arable land. Experts believe that the world’s population will grow to 11.2 billion people by the mid-2030s.
The population explosion will lead to a shortage of resources, in particular food. Earth is an isolated system, leaving us with two options:
People could stop reproducing. This has yet to happen in humanity’s history, so it’s safe to assume that people aren’t going to stop having kids.
We can make better use of the land we have.
Growing chambers allow researchers to develop high-grain products that use less land and produce more food. They also help to determine what regions of the world produce the best of a certain crop.
In the future, it’s almost guaranteed that food production will take a global approach to meet the needs of humanity. Certain nations will grow food for the sole purpose of exportation while importing others. We’ve seen the beginnings of this approach over the past 50 years, and that trend should continue.
Growth chambers allow researchers in the United States to test the viability of crops in Asia and Africa, and vice versa. This research is currently our best hope of staving off a food crisis that could lead to millions, if not billions, of people starving to death.
A Growth Chamber Helps You Make And Test Predictions
The hallmark of a good theory is the ability to make predictions about future events. In the case of agricultural science, this occurs by predicting such things as yield and survivability.
In the past, a scientist would develop a new type of grain that they believed could survive a shorter growing season. They would then have to test their crop in the real world. If their grain didn’t survive, it meant years of wasted work and hungry mouths to feed.
Now, scientists can make a prediction and use growth chambers to simulate a shorter growing season. If the prediction doesn’t hold true, they can begin working on a solution immediately.
This type of dynamic research leads to the creation of new crops. Researchers can adapt to changing climate patterns and other conditions. Water shortages could have devastated communities in the past. Now, we are able to plan ahead through the use of growing chambers and the variability they afford.

An environmental chamber is an enclosed space in which various environmental conditions such as heat and humidity can be controlled. Some chambers even account for corrosion through the introduction of salt spray into the chamber.
The size of these chambers can vary widely depending on the product that needs to be tested. Sizes can vary from a cubic foot to up to 12,000 cubic feet, which is large enough to drive a truck into!
What is an environmental chamber used for? The main function of environmental test chamberis to see how products handle operating in various environments. For instance, a car that runs very well in dry climates may stop working in humid environments.
Environmental chambers allow product manufacturers to test their products under a wide range of controlled conditions without having to physically travel all over the world. Environmental chambers that have been properly calibrated can generate reliable results that reflect real-world product performance.
So how do environmental test chambers work? The environmental chamber working principle is that all conditions can be controlled manually through a variety of mechanical processes. Temperature is controlled via electric resistor to either heat or refrigeration unit to cool the chamber.
To simulate the corrosive effect of living close to the sea, a salt solution is sprayed through a nozzle into the chamber, creating a fine mist that coats the entire product. Humidity in the test chamber can be simulate by two different methods: evaporation of water with a heat source or with ultrasound technology.
Water vapor is usually introduced into a test chamber via a steam generator which heats the water and creates steam. This steam rises to the top of the chamber, where it is cooled down again, raising the total humidity in the test chamber. This method is useful because it can generate high humidity in large chambers very quickly. The drawbacks are that it’s a very energy intensive process that can also affectthe temperature inside the test chamber.
Ultrasonic humidifiers don’t rely on heat to turn water into steam. Water vapor is created by running water on a diaphragm that vibrates at ultrasonic frequencies. The droplets formed by this method are extremely thin and can evaporate rapidly in the air in the test chamber. This humidified air is then transferred to the test chamber. This system used in the FDM test chambers is more efficient than heating system.
The main advantages of ultrasound system are:
– Greater performance in humidity producing – Increased energy efficiency – Silent system during operation – Cold operation, so it does not produce further heat – Immediate production of humidity
To ensure that the tests of products are accurate, manufacturers must know how to how to calibrate environmental chambers. Proper calibration of test chambers is essential to reliable and consistent results. Various environmental chambers will have different calibration processes, depending on how the environmental chambers work and what industry the chamber is being used in, so it’s vital to contact the manufacturer of the chamber to find out what the correct procedure is before starting the calibration process.
Growing Arabidopsis plant is highly influenced by climatic conditions but with some pro tips and the correct controlled conditions, you can get awesome results. Read on to find out the best method to growArabidopsis thaliana.
What is Arabidopsis thaliana plant?
Arabidopsisthaliana was the first plant to have the genome sequenced because it is a rarecase of a small one of approximately Mbp (Megabase pairs). Other than that, Arabidopsis thaliana is a small plant with white flowers that is native to the Eurasia zone.
The Arabidopsis can be grown in a wide variety of mediums like greenhouses, growthchambers and rooms, outdoors and in lighted shelves. If the growth method is properly applied and the maintenance plan is carefully followed, it enables the plant to produce seeds at a high rate. Also, it is considered a requisite for reproducible and accurate research.
Arabidopsis plant growth conditions
After three to fivedays of being planted, the seeds of most lines germinate. In a continuous lighting, water and nutrition and an approximate temperature level of 23°C, the first flowers can be expected within four to five weeks and seed harvesting in eight to ten weeks.
It is expected that environmental conditions in natural habitats create different phenotypes than in recreated ambient situations. It is important to bear this in mind when studying differences between them.
There are various ways to assist the Arabidopsis in its growth from a photoperiod point of view. The most recommended intensity is 120-150 µmol/m2sec. Although it can take more power, they might start to show purple leaves as a sign of too much light as one of the determining stress conditions that can lead to death.
The optimum temperature for the Arabidopsis to grow at its best is 22-23°C. It is not recommended to exceed the temperature range for Arabidopsis nor should temperatures dip below 16°C, especially in the early stages of growth. Older plants, which have passed the Rosette stage are able to withstand heat better than younger plants. At lower temperatures the plants are known to enter a vegetative state which delays flowering. Certain winter-annual variations of the plant, however, do require a period of cold in order to initiate the flowering process. Many of the young rosettes usually aged between 2 and 4 weeks, of the winter variations of the plant require being placed at 4°C for one to two months to accelerate the flowering process.
Keeping humidity uniform at around 50-60% is optimum for healthy plant growth. The relative humidity is a crucial influencer for the plant´s water needs. If the relative humidity is too high, above 90%, the most likely result is plant sterility. Some growers utilize low relative humidity, below 50% to achieve silique maturation.
Custom plant growth rooms
In most commercial growth facilities, it is easy to precisely control photoperiod, temperature, light intensity and often humidity too. Standard rooms can be equipped with additional temperature, ventilation, air conditioning, and lightning supplement growing conditions but are not as accurate as custom rooms. Greenhouses, on the other hand, can offer such services but are exposed to higher temperature deviations because of sunlight exposure. If the facility that is to be used for the growth of Arabidopsis was used with another species before, it would have to be cleaned to zero to avoid the use of pesticides or the loss of healthy plants because of infestation or pest.
Preservation of Arabidopsis seeds
The Arabidopsis small seedsrehydrate in a very rapid manner when they are exposed to any source of high humidity. If they happen to deteriorate, they lose vigor and if the process is not stopped, they lose the ability to germinate at all. The correlation between moisture, temperature and other unknown factors of cellular order determine the ´aging´ of the seeds. Seeds from Arabidopsis lines historically showedstrength and viability for long periods of storage if the conditions are properly maintained.
When the seeds are exposed at the ambient relative humidity and at room temperature, they lose viability in approximately a span of two years. However, if the temperature is of 4°C to -20°C, the dried seeds can be stored for decades and remain as vigorous as the first day. The humidity of the 4°C controlled-room for storage should be somewhere between 20-30% to ensure seeds are not rehydrated. If the goal is to store the seeds for longer periods of time (more than five years), sub-zero temperature and a maximum of 20% relative humidity.
This is the latest and portable environmental chamber that FDM realized for specific customer needs. It’s a next generation device configured with multiple advanced features realized for testing the samples with varying weathering conditions.

To summarize: it is small and portable, can be operated in any given conditions because of its ‘dynamic’ features. In others words, a smart environmental chamber.
As demand for electronic components, especially semiconductors, continues to grow rapidly, one of the challenges the industry faces, is the time taken to test those components. Traditionally, Temperature Humidity Bias testing, THB for short, has been the solution, but with that taking 1000 hours to complete it represented a significant delay, and this is where HAST testing, Highly Accelerated Temperature and Humidity Stress Test, offers significant advantages.
Taking between 96 and 100 hours per test, and often even less, the HAST test provides significant time savings that can have significant impact on business, and so has quickly become the most dominant of the endurance test methods for semiconductor devices. While primarily connected with semiconductor testing, HAST testing is used on a variety of both hermetically sealed and unsealed compact electronic components to provide fast testing results for a variety of situations and needs.
HAST testing standards
Time Is not the only difference, THB testing holds 85°C/85% R.h. condition as the samples are subjected to bias loads, however this has become less relevant today due to advances in the materials used in packaging and passivation.
By contrast, HAST test conditions use a high temperature of at least 100°C and usually around 105°C along with high relative humidity of around 85% in combination with high atmospheric pressure of up to 4 atmospheres. There is also a saturated version of the HAST test that uses 121°C temperature and relative humidity of 100%. If components are tested with power on, it is usually the unsaturated version with 85%RH. These environmental parameters provide an accelerated method of component reliability testing that quickly finds concealed defects that could result in failure during long-term use.
There are several standards for HAST tests from the IEC, JESD, JIS and JEITA, all indicate different combinations of temperature and RH, and are used for different situations. The most common are:
IEC 60068-2-66 – used in non-hermetically sealed, compact electronic components
IEC 60749-4 – Mainly used for semiconductors
JESD020C – Reflow soldering
JESD22-A104D – Temperature Cycling testing to cover component and solder interconnection testing
JESD22-B102E – Tests for accelerated moisture resistance, unbiased autoclave
JESD22-A108B – High Temperature Operating Life (HTOL) test
JESD22-A102C – Used for accelerated humidity resistance testing of non-hermetically sealed semiconductor-based devices
JESD22-A110C – Used for non-hermetically sealed semiconductor-based devices while powered to evaluate reliability
JESD22-A118 – Evaluates the reliability of unpowered non-hermetically sealed semiconductor-based devices
JIS C60068-2-66 – For testing compact electronic components
JEITA ED-4701/100 Method 103 – Tests the durability of semiconductors that are stored or used within high temperature and humidity-based atmospheres
Hast testing in practice
The Hast highly accelerated stress test uses dedicated design test chambers that are rapidly being deployed to replace existing THB testing chambers that use wet bulb/dry bulb mechanisms to control humidity accurately and consistently. That constant temperature/humidity chamber under high pressure is key to delivering fasterresults in all conditions.
HAST testing is particularly useful during product changes where adjustments could potentially accelerate metal corrosion, with results being obtainable so much faster than alternatives and as a result having a significant impact on development times. HAST testing is the best option for testing for any kind of moisture driven corrosion, with its testing capabilities providing shock accelerated conditions that provide a true test of components.
The ability to provide full tests of all components, evaluating insulation deterioration, overall performance including the performance of plastic sealed components in a variety of conditions, including through a vibration test, the HAST approach delivers the true shock test that gives a real insight into overall performance of the product.
With its flexibility and intensity providing a variety of testresults in a short space of time, HAST testing is well positioned for the modern production cycle. Crucially, the HAST testing process allows both saturated and unsaturated testing of components within the test cycle, and for plastic sealed components or others designed to be environmentally sealed, it provides a more streamlined, more effective outcome that enhances product development processes considerably.
Whatever testing standards are used, the ability to have tests completed in days, rather than months creates new opportunities for product development. By powering the agile testing process organizations are able to deliver faster responses to changing production needs, improving performance and delivering increased user satisfaction.

The Ultra freezer is one of the main tools used in research laboratories. The ULTfreezer safeguards biological samples important for research being carried out in laboratories, by keeping them at very low temperatures. The operating temperature can range from -45° C to -89° C.
Two versions are generally available: vertical cabinet or horizontal unit with access from above. The most common one is the vertical version, as laboratories are increasingly looking to save space to make it easier to move around. The internal storage volume of the low temperature freezer can also differ. It can start from an internal capacity of 200 litres up to a maximum capacity of 800 litres.
The Ultra freezer has shelves on the inside where research samples are placed. Each shelf is closed by an internal door so as to maintain the temperature as uniform as possible on the shelves where no sample is removed or placed.
In order to keep the cold stored inside the cabinet, between the external wall and the internal one, there is a pollutant free polyurethane insulation with high insulation coefficient, which keeps the temperature stable for several hours.
Another key element to maintaining the freezing status is the seal which is positioned around the entire perimeter of the main access door. The most efficient ones are silicone quadruple-step seals, which guarantee even greater temperature stability.
The main entry door, also insulated with polyurethane, guarantees the highest degree of coldness and is blocked by an external closure generally fitted with a safety key. The most practical laboratory freezers are equipped with pivoting wheels at the bottom, in order to make it more practical to move within the laboratory.
The most modern freezers are equipped with electronic PLC controllers, and a display that indicates freezing parameters. The entire control system is generally equipped with a back-up battery, which ensures the digital temperature display works even when there is a power failure.
How does the refrigerator circuit of an ultra freezer work?
The refrigeration systems can be a single high-power compressor hermetically sealed or two cascade compressors. In this second case, there are two refrigeration circuits connected so that the evaporator of one cools the condenser of the other, facilitating the condensation of the compressed gas in the first circuit.
Air-cooled condensers are generally used in laboratory refrigeration systems, consisting of tubular batteries (copper or copper-aluminium) arranged to provide as much surface heat transfer as possible. In Ultra freezers, the circulation of the cooling air is forced by an engine driven fan and the expansion of the refrigerant fluids is obtained by capillary tubes.
Evaporation takes place through steel plate heat exchangers, located inside the chamber, or by means of a coil. In horizontal freezers, the copper or copper-aluminium coil evaporator is placed along the walls and bottom, while in vertical freezers it runs along the walls and at the top. The coil in the room eliminates the problems of efficiency in the heat exchange of freezers with the coil in the insulation cavity.
Coolant fluids used in the ultra low temperature freezers
Refrigerant fluids are selected from gaseous chemical compounds that can easily be liquefied and characterised by certain properties such as high critical temperature and low critical pressure, limited hazard and toxicity. They are indicated by the letter R followed by a number that refer to the molecule’s atoms.
Each refrigerant system must be sealed and contain eco-friendly refrigerant HFC gas, free from CFC and HCFC as well as being non-explosive, non-flammable and non-toxic. The most efficient, environmentally friendly refrigerant fluids used in ultra freezers are typically R170, R23 and R290. With the new European Regulation UE 517/2014, the Ultra freezer manufacturers must to follow the guideline to allow its use even after 2030. So they must to use green refrigerants: R717 (Ammonia) R744 (Carbon dioxide) R170 (Ethane) R290 (CARE 40) Propane R600a (CARE 10) Isobutane R1150 (Ethylene) R1270 (CARE 45) Propylene
Which accessories can Ultra Freezer have?
The accessories generally supplied include: a CO2 and / or LN2 emergency system (both with independent power supply, probe and battery). In addition, in order to track room temperature, freezers are optionally equipped with a weekly charted temperature recorder, which has almost completely been replaced by digital ones.
In line with current international standards, the recorder is compulsory for freezers at -45° C and -86° C for the storage of blood products. Other accessories include: various kinds of steel containers, drawers and racks for storage of cryoboxes, microplates, blood bags and test tubes designed for low and very low temperature storage. Handling goods inside the ultra freezers requires you to wear suitable protective headgear, leather gloves to protect your hands and overalls and smocks to protect your body.
