Non-fixed Armored Thermocouple WRNK-121 WRNK-131 Brief Description

Non-fixed Armored Thermocouple WRNK-121 WRNK-131 is armored type no fixed device,Armored Thermocouple WRNK-121 WRNK-131 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, Armored Thermocouple WRNK-121 WRNK-131 is usually used with display, recorder and electronic regulator. Moreover,Non-fixed Armored Thermocouple WRNK-121 WRNK-131 can also be the temp sensor element of assembly-type thermocouple. Armored Thermocouple WRNK-121 WRNK-131 can measure temp of liquid, stream, gas and surface of solid range 0℃~1000℃ in all production processes. It is as per GB/T18404-2001 standard.
