Type E Thermocouple Wire Description

NiCr- CuNi thermocouple (type E) is also named NiCr- Constantan thermocouple. The main chemical composition of positive leg NiCr (EP) is Ni: Cr≈90:10; negative leg Constantan (EN) is Cu: N≈ 55%: 45%. The operating temperature range of type E thermocouple is -200-900°C.

Type E has a stronger signal & higher accuracy than Type K or Type J at moderate temperature ranges of 1,000F and lower. Type E is also more stable than type K, which adds to its accuracy.
