All of our thermocouple wires and assemblies are made to international standards; they are tested in our UKAS accredited calibration laboratory and you’ll receive a certificate detailing emf outputs.

Our type R, S and B thermocouple wires are supplied in accordance with the emf and temperature relationships detailed in IEC 60584-1 (BS EN 60584-1) based on the International Temperature Scale of 1990 (ITS-90). All thermocouples can also be supplied based on IPTS-68 if required.
