Platinum Thermocouple Wires are used for manufacturing of thermocouples. In a thermocouple two different metal wires are joint at one end [Hot Junction] and kept open at other end [Cold Junction]. When the Hot Junction is exposed to higher temperature, electromotive force is generate at cold junction. By measuring the emf at cold junction temperature at hot junction can be determined. Thermocouples play a vital role in a number of industrial fields for temperature measurement.

JIS tolerance Class 2. Class 1 available as option.

Confirming to ITS90.

Calibration certificate available at palladium point.
