Thermocouples (TC) are temperature sensors composed of two dissimilar metals fused together that produce a change in voltage when heated. This change in voltage is interpreted as a change in temperature. The composition of the TC is dependent on the users temperature requirements.

Mellen thermocouples are carefully packed and inspected in individual carriers designed to arrive protected and secure. The cleanly designed packaging allows for easy shipment and storage.
