Product Description
Type J Thermocouple Probe (316 Stainless Steel Sheath, M20×1.5 Thread, IP65)
Type J thermocouple probe from Huona New Material is a robust industrial temperature sensor featuring a Type J (Iron/Constantan) thermocouple junction, a 316 stainless steel protective sheath, and a brass connection head with IP65 rating. Manufactured with precision welding and high-quality insulation, it delivers stable thermoelectric performance across -40℃ to 750℃ (continuous) / 800℃ (short-term). Ideal for petrochemical processing, industrial furnaces, and HVAC systems, it offers excellent oxidation resistance, reliable performance in harsh environments, and long-term durability.
