Item Type: K-Type Thermocouple_x000D_ Index Number: K_x000D_ Temperature Measurement Range: 0-200_x000D_ Probe Material: Stainless steel_x000D_ _x000D_ Probe Specification: Approx. 4 x 30mm / 0.2 x 1.2in(diameter x length)_x000D_ Wire: Approx. 2 x 7 x 0.2mm / 0.08 x 0.28 x 0.01in (the surface is imported soft silicone)_x000D_ Terminal: U-shaped terminal_x000D_ The Basic Principle of Thermocouple Temperature Measurement: Two conductors of different materials or semiconductors A and B are welded together to form a closed loop. 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_x000D_ 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 contact with the measured object
