Our purpose-built United Kingdom Accreditation Service (UKAS) certified laboratory, based in Aberdeen, provides a variety of calibration services, covering an extensive range of electrical and pressure instruments.

We also specialise in the calibration and repair of dimensional metrological instruments such as micrometres, dial gauges and depth gauges using computerised calibration to tolerances of 10-4. Using our mobile service van fleet, we can offer both pressure calibration and torque recalibration at our clients’ premises.
