Why Would I Need a Calibration?

Calibration is the process of comparing your measuring instruments and other related tools with a standard of known accuracy & against manufacturer’s specification. The purpose of the calibration process is to ensure that the readings given by your measuring equipment are accurate to those of the standard to ensure that your instruments are not giving incorrect values.

After the calibration and testing process, your test instruments will be awarded a traceable certificate that shows the accuracy and reliability of your measuring instruments.
