Abrasive Resistance ThermocoupleBased on the WR and WZ series, the insertion part of the protective casing can be made in full or in part.
Abrasion-resistant, scrub-resistant, and corrosion-resistant.
Long lifespan. Can be used for over 6 months at high temperatures, and over 8 months at low temperatures.
Thermocouples and thermistors are designed with a armored structure.
