What is calibration and why is it so important?


You surely have heard the term ‘calibration’ many times, but do you know what is calibration and why it is so important? Well, you are in the right place and this post will tell you how the calibration service works. To know more, read till the end.

What is calibration?

Calibration is a procedure through which we compare the reading of a piece of equipment or system with another system or equipment which is calibrated following a certain parameter. The international standard for the official recognition of Testing and Calibration Laboratories is ISO/IEC 17025. It involves both technical necessities and quality management system necessities.

Why calibration is so important?

Calibration it immensely crucial in all places where measurement is crucial. It ensures the accurateness and quality of measurement. In many cases, it is very common that the output result may differ from the actual result. This issue often occurs while measuring temperature or humidity.

To avoid this, it is highly recommended to calibrate measuring devices on a regular basis. So, the primary purpose of calibration is to eliminate measurement flaws while ensuring optimum quality and accuracy of the measurement.

Food industry: Within the food industry,  if the food temperature measuring devices are not calibrated properly, it might lead to bigger issues such as food safety concerns, legal hazards, breach of HACCP, etc. And as a consequence, it can spoil the reputation of a business enormously or lead to the cancellation of a food license.

Manufacturing: Calibration is also highly important in the manufacturing industry. This industry uses a lot of equipment like gas detection monitors, heat stress monitor, alarm systems, vapor detector monitors, indoor air quality testing monitors.

That’s why a critical alarm system or other gas detection devices should be calibrated from a reputed calibration service to avoid any possible fluctuation in measurement. Misguided or faulty calibration can result in death, injury, or create disastrous environmental concerns.

How to calibrate a device?

Usually, calibration refers to the process of adjustment of the measuring device along with setting a specific value based on a set of parameters. But in actual, there are two courses of action; calibration and adjustment. So, if you are looking for a service, you must know which service you specifically want and how the process of calibration will proceed.

For instance, think of a digital thermometer with an external temperature probe. To calibrate it, service providers may apply a simulated temperature value by attaching a test instrument with it and recording the result to calibrate it as per the standard.

However, if you want to conduct a thorough and more precise calibration to satisfy your real-world usage needs, then your favored technique would be testing both the digital thermometer and the temperature probe, which is known as ‘system test’.

How often you require calibration?

As per the industry set practice, you need to calibrate your measuring devices yearly. However, the best way to decide the frequency of calibration is to monitor the calibration test results on a constant basis.
