Liquid Measuring 50mm x 5mm PT100 Type Earth Thermocouple Probe 1 Meter 3.3ft
A thermocouple is a device consisting of two different conductors (usually metal alloys) that produce a voltage proportional to a temperature difference between either end of the pair of conductors.Widely used in science and industry applications including temperature measurement for kilns, gas turbine exhaust, diesel engines, and other industrial processes.
