Product Details

Product Description

Thermocouple’s long-time stability and service life will be up to outside protection tube. Thermocouple shielded by silicon nitride thermocouple sheath will quickly react to temperature due to its good thermal conductivity and thinner wall thickness. Silicon nitride thermocouple protection tube is for continuous temperature measurement and protect thermocouple without erosion.
