Product Description

Type E Thermocouple Wire with NiCr/Constantan 
 
TYPE E (Chromel vs Constantan) may be used in oxidizing, inert or dry reducing atmospheres, or for short periods of time under vacuum. Must be protected from sulfurous and marginally oxidizingatmospheres. Produces the highest EMF per degree o any standardized thermocouple.
