Thermocouples 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 emperature.The calibrations are K, N, E.J, T, S, R, B. Each calibration has a different temperature range.
