Calibration

Any measurement equipment is required to be calibrated every year according to ISO quality standards.

If you are required to calibrate your temperature measurement equipment installed in order to conform to the Heatwave Plan then any system put in place must take calibration into account.

Fortunately, any system installed does not need to run 24/7/365 so onsite calibration is not required.

Many thermometers are sold with a manufacturer’s certificate of calibration. The certification will last a single year and needs to be renewed each year.

Your own quality system may specify a specific calibration standard that must be adhered to such as UKAS. In which case, you will need to purchase thermometers and UKAS calibration as an extra cost item. Each year when the thermometers are not in use you will need to re-calibrate your thermometers to the UKAS standard.

Any system you decide to commission needs to take into account yearly re-calibration and especially the extra cost element over the lifetime of the system.
