Thermocouples consist of two dissimilar metal wires joined at a hot junction; as temperature changes, a millivolt signal is generated. ProSense type J and type K probes with IP66 NEMA 4X connection heads and spring-loaded probes are used to assure target contact. Measuring ranges are available from 32 to 1700 degrees F.
