Why is Balance and Scale Calibration Important?


Balance or scale calibration is essential to achieve accurate weighing results. Ignoring this important service activity turns measuring into guesswork. In other words, it is negligent to weigh with a non-calibrated balance or scale. The accuracy of balances and scales becomes less reliable over time. This is the result of normal wear and tear caused by regular use and external factors such as mechanical shocks or hazardous environments. This may lead to a rather quick degradation or deterioration over a longer time. Periodically scheduled balance calibration in combination with frequent routine testing greatly enhances the life time of your balance or scale and its weighing accuracy.


But what is calibration? In simple terms, calibration is a quantitative comparison. To check the reading of a balance or scale, a reference weight is placed on the pan. The error is defined as the difference between the measured value (the reading) and the true value (the reference weight).


How Do I Choose a Company to Calibrate My Scale?

All of this information won’t mean anything if it’s not documented and “traceable” to a primary standard. What does this mean, exactly?

Documentation is pretty straightforward. You must have a calibration certificate to show calibration results. If any part of the documentation isn’t there, the calibration is not traceable, and therefore, is like it never happened.

More importantly, it needs to be traceable to a primary standard. What is a primary standard? It’s the standard set by NABL. This does not mean you need to have your instruments calibrated by NABL, but it does mean that the company you use needs to have test standards that are calibrated by an unbroken chain of calibrations, traceable to NABL. Using a calibration company that is accredited to the ISO 17025 standard provides this assurance of calibration traceability as well as proficiency in performing the calibrations.

Given the importance of this information, you can see why it’s advantageous to select a company that specializes in calibration — and why it’s so important to choose that company carefully.

There are two types of calibration companies — those that are accredited and those that are not. Why does it matter? The ones that are accredited are traceable.

That means you can be confident that the laboratory documents calibration results, has a system and procedure that is in working order and has employees that are educated and skilled in everything from the calibration process to the documentation of results. It also means that to keep their accreditation, they have to be audited on a regular basis and pass so that you can be confident in their technical proficiency and documentation abilities.
