Based at our factory in Sheffield, our accredited laboratories are available to provide either on-site or in-house calibration to either UKAS or traceable national standards. We cover Temperature (up to 2,200 °C), Pressure (up to 1,200 bar), Flow (up to 2,500 L/min) and Electrical parameters, providing full certification using the latest technology. 

Our team of experienced on-site engineers hold accreditation for the on-site calibration of equipment including autoclaves, furnaces, thermocouples, RTD probes, scales, balances, ovens, chambers, indicators, controllers, pressure and electrical instruments. We cover the full spectrum of industry sectors.

We are Aerospace Heat Treatment Specialists, from the supply of a single thermocouple to fully managed service contracts, by working in partnership with our customers we can assist in obtaining and maintaining NADCAP approval.

All calibration standards used meet the requirements of Table 3 of the current version of AMS 2750, whether in the laboratory or on site, ensuring full compliance with the specification.

We supply thermocouples calibrated and certified to meet the requirements of Table 1 of the current version of AMS 2750 appropriate to customer specified usage.

Certificates generated are designed to meet the requirements of the current version of AMS with the option of UKAS certificates for maximum user confidence.
