Type E thermocouple|china E Type thermocouple WREK is a low-cost metal thermocouple. The positive electrode (EP) is: nickel-chromium 10 alloy, and the negative electrode (EN) is copper-nickel alloy. The nominal chemical composition is: 55% copper, 45% nickel and a small amount of Manganese, cobalt, iron and other elements. The operating temperature of this thermocouple is -200~900℃.
Features of E-type thermocouple

The thermoelectromotive force is large and the sensitivity is high. It is the best among the thermocouple types, better than the K-type thermocouple. It is suitable to be made into a thermopile to measure small temperature changes. High sensitivity, but not very sensitive to the corrosion of high humidity atmosphere, suitable for low humidity environment. The E thermocouple also has the advantages of good stability, better oxidation resistance than copper-constantan and iron-constantan thermocouples, and low price. It can be used in oxidizing and inert atmospheres and is widely used. E-type thermocouples cannot be directly used for sulfur at high temperatures, and the uniformity of thermoelectric potential is poor in a reducing atmosphere.

Type E thermocouple|china E Type thermocouple WREK Insulation resistance for normal temperature
In terms of the sheath thermocouple, the environment temperature is 20 + 15℃, the relative humidity is not more than 80%, the test voltage is 500 + 50V(DC), the insulation resistance between electrode and outer sleeve≥1000MΩ.m. That is to say, the insulation resistance for sample of 1m is 1000MΩ; the insulation resistance for sample of 10m is 100MΩ.
