Application
Usually display instruments, recording instruments, computer and other ancillary uses. Direct measurement of the production process in the range of 0 ºC -1300 ºC liquid, vapor, gas and solid surface temperature.
Works
When sheathed thermocouple electrode composed of two different conductor materials when measuring end and the reference junction temperature difference, it will generate thermoelectric power, work thermoelectric power meter will show the corresponding temperature value
Feature
1,Assembly is simple, easy to replace

Temperature insulation resistance
Armored even at an ambient temperature of 20 ± 15 ºC, relative humidity less than 80%, the test voltage is 500 ± 50V (DC) insulation resistance between the electrode and the jacket pipe ≥1000MΩ.m.
That is 1m long insulation resistance of the sample is 1000MΩ.
10m long insulation resistance of the sample is 100MΩ.
