An environmental chamber is a climate controlled chamber used to test the effects of temperature on certain objects, such as biological devices, industrial products, electronics and automotive products. This allows the user to see how the product will perform under certain temperatures, which is vital in certain industries, especially aviation. Since these types of work are highly regulated and the measurements need to be just right, it’s important to have you environmental chamber calibrated on a regular basis. So, what does all that entail?
In this whitepaper, we will take a look at the 5 benefits of environmental chamber calibration, environmental chamber calibration frequency, what should be included in calibration and how to choose a calibration lab.
5 BENEFITS OF ENVIRONMENTAL CHAMBER CALIBRATION
Environmental chamber calibration is of extreme importance. Like any other measuring device, an environmental chamber’s calibration can and will drift over time. For this reason, it is vitally important to calibrate an environmental chamber on a regular basis. By doing so, many benefits can be reaped, such as:
Calibration of an environmental chamber ensures the instrument is making consistent measurements. Without calibration, an environmental chamber has a high chance of displaying incorrect readings.
Environmental chambers that are calibrated frequently are guaranteed to be accurate. When calibration is not performed on an environmental chamber, risk of improper measurements are likely.
Calibration of an environmental chamber establishes instrument reliability. When a chamber is calibrated, it can be trusted to perform properly and measure accurately.
When an environmental chamber is calibrated, a paper trail is left behind. This paper trail aids in mapping the instruments drift, which aids in creating an environmental chamber calibration interval.
Calibration of an environmental chamber ensures the instrument is maintaining its adherence to industry standards and government regulations. This in turn, ensures safe and proper use of the instrument.
All five of the above benefits are easy to acquire if you take the time to properly calibrate your environmental chamber. When an environmental chamber is calibrated, the overall quality of the instrument and its measurements are boosted. This in turn benefits your bottom line. While calibration of instruments may seem expensive upfront, it actually saves your company money by ensuring calibration errors are minimized. Errors from incorrect calibration of an environmental chamber are likely to cost your company more money in the end and put a damper on your company’s reputation.
ENVIRONMENTAL CHAMBER CALIBRATION FREQUENCY
Environmental chamber calibration is performed to ensure the overall functionality of equipment is accurate and reliable. Like many other measuring instruments, an environmental chamber is prone to drifting and damage over time which impacts its performance. In order to maintain an environmental chamber’s overall effectiveness, calibration needs to be completed frequently. With regular calibration, an environmental chamber will have minimal performance risks and reduced uncertainties.
Environmental chamber calibration intervals should be based off the following factors:
Mostly all environmental chambers will come with a manufacturer recommendation of when to calibrate the instrument. While these recommendations offer a great start for creating the right frequency, it is important to keep other factors in mind.
BEFORE/AFTER A LARGE PROJECT
Ensuring an environmental chamber is performing accurately is extremely important before starting a big project. Keep in mind, equipment that has undergone any major project for an excessive period of time should also be calibrated. This is because frequent and heavy use can cause performance and accuracy drifts.
Sometimes equipment trauma is hard to avoid. One major trauma common with an environmental chamber is internal overloads. These overloads can occur due to a high volume of usage. To ensure that an environmental chamber is performing to the best of its ability after an overload, it is important to re-calibrate the chamber before continued use.
AMOUNT OF USAGE
Ideally, an environmental chamber should be re-calibrated based upon the amount it is used and for how long it has been used for. This amount varies depending upon the equipment owner; therefore, it is important to base environmental chamber calibration schedules around your own personal usage.
When creating a schedule for your environmental chamber calibration, you should take into account all of the factors listed above. Accuracy of an environmental chamber is of extreme importance and effects the overall quality of the equipment. To ensure an environmental chamber is accurate, reliable and above all safe, calibration should be performed frequently. In the end, failure of an environmental chamber due to lack of calibration could cost more than calibrating your equipment regularly.
WHAT SHOULD BE INCLUDED IN ENVIRONMENTAL CHAMBER CALIBRATION
When looking for an environmental chamber calibration provider, it is important to ensure that all necessities are included in your service. To guarantee quality calibration services, the following should be included in your environmental chamber calibration:
ACCURATE MEASUREMENT TESTING
What’s the point of even calibrating your environmental chamber if you’re not guaranteed accurate and reliable results? When choosing a provider, it is essential to choose someone who can give you quality results. Accurate measurement testing is the key to quality calibration.
MEASUREMENT OF UNCERTAINTY RATIO
Choosing a provider that calculates the measurement uncertainty ratio of your environmental chamber can be very beneficial. Knowing exactly what the uncertainty ratio of your environmental chamber is aids in more accurate measurement results. It also helps determine when your environmental chamber calibration is starting to drift.
MEASUREMENT AND CALIBRATION TRACEABILITY
Many people take traceability for granted when it really is one of the most important keys to reliable calibration. When measurements and calibrations are traceable, it means they can be traced back to national standards and are the highest of quality.
Quality environmental chamber calibration services will provide you with a calibration certificate. This certificate will be able to identify information regarding the calibration and will serve as proof that your environmental chamber has been calibrated.
To ensure that all four factors are included in your environmental chamber calibration service, you should choose an accredited calibration lab. By choosing an accredited lab, accurate measurement testing, measurement of an uncertainty ratio, traceability and a calibration certificate will all be included in your environmental chamber calibration service.
CHOOSING A CALIBRATION LAB
When looking for a provider for your environmental chamber calibration service, it is important to seek a facility that is competent and complaint with a high set of standards. A quality facility will provide topnotch service with a handful of components included to give you accurate and reliable results. To assist you in your search for a provider, we have created a set of guidelines to consider and have listed qualities needed to ensure your environmental chamber is calibrated precisely.
ACCREDITED CALIBRATION VS. NON-ACCREDITED CALIBRATION
Any calibration needs to be performed by either an accredited calibration lab or a non-accredited calibration lab. When choosing which type of laboratory to use for your environmental chamber calibration, it’s important to keep in mind exactly what an accredited calibration lab is and why it is has been deemed accredited.
In short, an accredited calibration lab is only deemed accredited after it has “passed” an assessment by an accrediting body. The accrediting body only declares a lab accredited after it has thoroughly assessed the lab in three areas, personnel, lab environment and traceability compliance. When a lab is accredited, the following is guaranteed:
- Personnel with the highest level of technical competence – in regards to the Scope of Accreditation.
- A monitored lab environment that will not alter calibration results.
- Precise equipment traceability (in most cases through NIST).
Accredited calibration labs, unlike non-accredited calibration labs, live, breathe and eat maintenance. For this reason, choosing an accredited calibration lab, over a non-accredited calibration lab, will ensure your environmental chamber calibration is performed precisely. Notably, not all unaccredited calibration labs are equal, therefore not all calibrations are equal. By choosing an accredited calibration lab for your environmental chamber, you are guaranteeing accuracy of your calibration services.
THE BENEFITS OF CHOOSING AN ACCREDITED LAB
- Technically Competent Personnel
- Confidence in Calibration Results
- Minimal Risk Factors
- Equipment Traceability
- Monitored Lab Environment
- Required Measurement Uncertainty
Accredited calibration labs are guaranteed to serve the following factors above. This is because they are required to meet the highest industry standard, ISO/IEC 17025.
