Thermocouple grade wire can be used as an actual thermocouple to measure temperature or to accurately carry the millivolt signal from a thermocouple to an instrument. Since thermocouple grade wires (excluding R, S, & B which are compensating only) can be used as a thermocouple to directly measure temperature. They are calibrated for many different temperature ranges. www.tcproducts.com a division of Marsh Bellofram www.marshbellofram.com 1-800-727-5646 Thermo-Couple Products Co. 1 Wire
