 WREK-221 WREK-222 Splash proof Armored Thermocouple Brief Description

 WREK-221 WREK-222 Splash proof Armored Thermocouple is armoured type with fixed thread connection, splash proof type, WREK series armoured type Type K  WREK-221 WREK-222 Splash proof Armored Thermocouple 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-221 WREK-222 Splash proof Armored Thermocouple is usually used with display, recorder and electronic regulator. Moreover,  WREK-221 WREK-222 Splash proof Armored Thermocouple can also be the temp sensor element of assembly-type thermocouple. WREK-221 WREK-222 Splash proof 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.
