The bimetal thermometer works on the principle that two different metals expand differently when the temperature changes. The main component of the industrial bimetal thermometer is a multi-layer metal sheet composed of two or more metal sheets laminated together. In order to improve the temperature

The bimetal thermometer combines two metals with different linear expansion coefficients, and one end is fixed. When the temperature changes, the two metals have different thermal expansions, driving the pointer to deflect to indicate the temperature. This is a bimetal thermometer. The temperature m

The ear thermometer uses a built-in sensor to measure the infrared energy radiated by the eardrum, and then it can accurately determine its surface temperature. Because the eardrum is in the deepest part of the external auditory meatus, it can more accurately reflect the body temperature.When measur
