Product Description
Chromel Constantan Thermocouple Bare Wire 20AWG
This precision thermocouple bare wire features Chromel-Constantan construction in 20AWG gauge, designed for extension thermocouple cable applications requiring reliable temperature measurement from -200°C to 900°C.
Product Overview
Thermocouple wire enables electronic temperature measurement through the thermoelectric effect. When two dissimilar metals are joined at a sensing point and connected to a voltage measuring instrument, they generate a millivolt signal proportional to temperature differences between junctions.
