OEM Single / Double NiCr-NiSi Assembly K Type Thermocouple WRR2-120

assembly-type thermocouple

As the sensor of the temperature measurement, assembly-type thermocouple is used with displays, recorders and electrical adjuster completely. It can measure the temperature of liquid, vapor, gas and the surface of solid from 0℃ to 1800℃ directly. According to national regulation, we have manufactured copper- copper nickel, iron-copper nickel etc. type of thermocouple since 1987. They are all in line of IEC international standard graduation.

"The Pico 4's visual clarity is fantastic once you dial in the IPD correctly. The manual adjustment is smooth, and finding that sweet spot makes all the difference. No more eye strain during long sessions. Highly recommend taking the time to set it up properly!""The Pico 4's visual clarity is fantastic once you dial in the IPD correctly.
