Product Description
Tankii 0.5mm Chromel Constantan wire E type thermocouple wire EP EN
Stock size: EX cable 2*0.2mm with fiberglass insulation and jacket with low price.
NiCr- CuNi thermocouple wire (type E) is also named NiCr-Constantan thermocouple wire.
It has a stronger signal & higher accuracy than the Type K or Type J at moderate temperature ranges of 1,000F and lower.
The type E thermocouple wire is also more stable than the type K, which adds to its accuracy.
Type E thermocouple wire has the largest EMF output and highest sensitivity, so it is ideal for measuring small temperature change.
It also has good stability in the low temperature range up to 300ºC, and good property of anti-corrosion in humidity atmosphere.
It is recommended for oxidizing or inert atmospheres, but cannot be used directly in reducing atmosphere and atmosphere with sulphur gases.
