Expert care for all brands

ExpressCal is an expert repair and calibration service for all brands of electrical test equipment. A sister company to Kewtech Corporation, ExpressCal has significant insight into the technical functions of test equipment. Our engineers have been involved in the design of test equipment so they really understand and appreciate the technology and are in an expert position to provide both repair and calibration services.


Professional service

It is vitally important that your test equipment is regularly calibrated in order to ensure its accuracy and reliability. Over time, the accuracy of your tester can drop and that is why we recommend getting your testers calibrated annually.

There is a detailed and precise procedure to the calibration process which requires time and care to be spent with your tester to ensure reliable readings. This must only be undertaken by an accredited laboratory with all calibrations traceable back to the National Standards and procedures detailed in BS EN/IEC17025:2017 and carried out by suppliers who are ISO 9001:2015 certified.

Failure to ensure your equipment is calibrated with a recognised and certified calibration laboratory could result in compliance and safety issues, litigation issues, increased downtime and the degrading of your equipment’s performance.

We realise that your equipment is a valuable tool. That is why we look to offer a 72 hour turnaround where possible on calibrations. However, if you are able to drop your meter into us at Doncaster (DN2 5TB), we can offer a same day calibration.
