Product Description

Product Description:
Thermocouple bare wire is used at temperatures up to 1260°C (2300°F). MICC thermocouple
 bare wire is supplied with bright or oxidized surface according to standard or special EMF requirements. 
Each individual lead is calibrated against platinum and the EMF values are shown on each coil or spool.
