The surface thermometer used in where?

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 500 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. The surface thermometer used in where? Instrument answer: surface thermometer to use on the industrial pipeline, chemical equipment, used to measure the surface temperature, special thermometer is pipes. Now commonly used in industry surface models have ST200DM double magnet thermometer thermometer, ST221SM thermometer, single magnet ST221SS spring thermometer. ST200DM double magnet thermometer ST221SM single magnet ST221SS spring surface thermometer thermometer thermometer use note: cannot 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 loaded surface thermometer again to pay attention to when using 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.
