Calibration

Calibration is an essential element of the activities of any company if quality is to be taken seriously.

GNW are able to offer calibration services for all pressure, temperature, electrical, environmental, metrological and measuring, weighing and force, flow and tank contents instrumentation. Whether this be in an industrial or laboratory setting.  We offer a quick turn around on all items.

The need for instrumentation to perform consistently, to a high accuracy throughout its working life, can only be fulfilled if they are periodically calibrated. This is to ensure that they are within designated permissible limits of error. However, one of the most important part of a calibration system is the suppliers' traceability!

GNW are certificated to BS EN ISO 9001:2015 and audited by WCS, and we provide a full calibration service in accordance with these standards. 

If you require a UKAS accredited calibration, GNW can provide this service via our sub-contract arrangements with our third-party partners who have been UKAS accredited.
