Product Desprition
E type thermocouple wire (type EP EN)
TYPE E (CHROMEL vs Constantan) may be used in oxidizing, inert or dry reducing atmospheres, or for short periods of time under vacuum. It Must be protected from sulfurous and marginally oxidizingatmospheres.
Type E thermocouple 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.
