UKAS Calibration Services

A broad range of instrument calibration services

As temperature and humidity specialists, we recognise that calibration is a key factor that can influence the accuracy with which a piece of equipment is running.

This is why we’ve spent over two decades fitting out an end-to-end calibration laboratory and partnering with brands that offer market-leading calibration equipment. This builds our reputable portfolio of UKAS calibration services and instrument calibration services to meet various requirements. 

Our team of experts offer exceptional guidance to support outsourced UKAS calibration services. 

Temperate calibrations can be performed across a variety of fixed points and variable ranges too. If you're interested in finding out about the capabilities of our labs outside of the services below, contact our team of engineers at [email protected] for a quick response.
