WREK-481 WREK-482 Little junction box Armored thermocouple Brief Description

WREK-481 WREK-482 Little junction box Armored thermocouple is armoured type with fixed flange connection, little junction box, WREK series armoured type Type K Thermocouple WREK-481 WREK-482 has advantages of being able to bend, high temp resistance, quick thermal response time and being sturdy and durable etc. Like industrial assembly-type thermocouple, as sensor of temp measurement,  WREK-481 WREK-482 Little junction box Armored thermocouple is usually used with display, recorder and electronic regulator. Moreover,  WREK-481 WREK-482 Little junction box Armored thermocouple can also be the temp sensor element of assembly-type thermocouple. WREK-481 WREK-482 Little junction box Armored thermocouple can measure temp of liquid, stream, gas and surface of solid range 0℃~700℃ in all production processes. It is as per GB/T18404-2001 standard.
