Surface thermometer must be fixed on the surface? Following instrument for you answer: answer: surface thermometer have two, spring thermometer thermometer and magnet spring thermometer can use spring fixed on the pipeline, the surface temperature of the measuring pipe; Containing magnetic behind magnet thermometer, can be directly adsorption on the metal surface. Surface thermometer use note: magnet thermometer can't adsorption on the stainless steel material, must pay attention to surface temperature sensor is installed, it will determine the surface temperature measurement of accurate or not. Spring type surface thermometer when use should pay attention to the length of the spring and the diameter to be fixed. In addition, when using, pay attention to clean up and check, regularly test the measured values. Surface thermometer is to rely on the principle of the double metal heat bilges cold shrink principle of sensors to work, by contact spring or magnet at the bottom of the thermometer to measure the metal surface and reading. This type of double metal surface thermometer can range from - 40 c to 400 c, the precision can be in for some using occasions for accuracy is not high, can yet be regarded as a money and cheap thermometer of beauty.
