Land Calibration Laboratory – Dronfield

The LAND calibration facility was formed so that customer requirements for temperature calibration can be satisfied.

The laboratory offers a comprehensive service for the calibration of temperature sensors and sources including; radiation thermometers, thermal imagers, thermocouples and blackbody sources.

he LAND laboratory, in the UK, was the first to be accredited in 1970 for the issue of Calibration Certificates in the field of thermal measurements and was also the first to be accredited for the issue of certificates that meet the requirements of ISO 17025.


Re-Calibration Reminder Service

Regular traceable calibration is essential for temperature measuring equipment if accuracy is to be maintained. Many authorities, particularly the Ministry of Defence and Rolls Royce specify the frequency of re-calibration for sub-contractor’s instruments.

Remembering re-calibration dates is often a cause of trouble and concern, particularly when more than one type of device is used, as thermocouples, radiation thermometers and potentiometers all have different re-calibration frequencies.

In order to remove this burden from the instrumentation engineer we have introduced a Re-calibration Reminder Service. With this service customers automatically receive a written reminder when any item of temperature measuring equipment is due for re-calibration.

Emissivity Determination

For accurate temperature measurement with radiation thermometers the emissivity of the measured surface must be determined.

For customers who do not have the necessary equipment and know-how to obtain this vital parameter LAND provide a service which is fast, convenient and accurate.

Simply send a sample to our laboratory together with your order.

We will conduct the required tests and return the sample with the emissivity information. Ideally the sample should be supplied as a 50mm diameter disc. We will extract a suitable sample from your material in our laboratory as an extra service.
