When there is a temperature difference between the two attachment points 1 and 2 of conductor A and B, the situation of generating electromotive force and forming a current in the loop is called the thermoelectric effect. Thermocouples use this effect to work Application: Thermocouples are widely used in various enterprises and institutions such as petroleum, water conservancy, chemical industry, metallurgy, electricity, environmental protection, etc., to achieve temperature measurement and direct with the measured object Size: Approx. 22mm / 0.9in, 11mm / 0.4in Package List: 1 x K-Type Thermocouple Package List 1 x K-Type Thermocouple
