The importance of calibrate a Climatic chamber

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:

  1. how the calibration should be done
  2. the frequency of the calibration
  3. factors to consider in choosing a calibration lab
  4. 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.

What should be included in calibration service

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
      • Equipment traceability
      • Supervised lab environment
      • Required measurement uncertainty.

Accredited calibration labs are required to meet highest industrial standard, ISO/IEC 17025
