Thermocouple are used in industry for measuring the temperature of gases, liquids or solid surfaces etc., Its usually assembled with indicators, recorders or computers.
A thermocouple consists of two dissimilar metals joined together at one end. When the junction of the two metals be cooled or heated and a voltage is produced that can be correlated back to the temperature,
Shangyu Shenzhou Instrument Co., Ltd providing Thermocouples are manufactured in different combinations of metals. The calibrations are K, N, E.J, T, S, R, B. Each calibration has a different temperature range.
