A thermocouple is a temperature sensing element that can measure temperature directly. Two conductors or semiconductors A and B of different materials are welded together to form a closed loop. When there is Thermocouple Temperature measurement temperature difference between the two attachment points 1 and 2 of conductors A and B, an electromotive force is generated between the two, so a large current is formed in the loop, which is called the thermoelectric effect. Thermocouples use this effect to work.
The thermocouple temperature measurement has a wide range, relatively stable performance, and high measurement accuracy. The thermocouple can be in direct contact with the measured object and is not affected by the intermediate medium, so its response time is very fast. Thermocouples have flexible response to temperature changes, reliable performance, good mechanical strength, long service life and easy installation, so thermocouples are widely used in life.

Focusens thermocouple series products mainly cover K-type thermocouples ,T-type thermocouples and J-type thermocouples with temperature measurement below 600 degrees. The application scenarios mainly focus on household, medical and industrial fields, such as temperature measurement of medical reagents and incubators. Food temperature probes for medium and high temperature cooking steam ovens, medium and low temperature sous vide low temperature nutrition cooking equipment, temperature measurement, control and protection of mechanical and electrical components of equipment.
