Chromel constantan Thermocouple Wire (type E)
The Type E thermocouple is composed of a nickel-10% chromium (+) versus a nickel-45% copper (-) wire. This Type of thermocouple can be used in oxidizing or inert atmospheres with a service temperature range of -200°C to 900°C (330°F to 1600°F). The Type E thermocouple can be used successfully in subzero applications due to high corrosion resistance to high moisture environments. Out of all of the different types of thermocouples, The Type E has the highest EMF output per degree.
