Type E Thermocouple

(Chromel / Constantan)

0 to 900°C, (32 to 1652°F)
Type E Thermocouple

Composed of a positive leg, which is approximately 90% nickel, 10 chromium and a negative leg, which is approximately 95% nickel, 2% aluminum, 2% manganese and 1% silicon.

When protected by compacted mineral insulation and appropriate outer sheath, Type E is usable from 0 to 900°C, (32 to 1652°F). This Thermocouple has the highest EMF output per degree of all recognized thermocouples. If the temperature is between 316 to 593°C, (600 to 1100°F), we recommend using type J or N because of aging which can cause drift of 1 to 2°C, (2 to 4°F) in a few hours time. For applications below 0°C, (32°F), special selection of alloys are usually required.

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