What kind of measuring surface temperature of the thermometer

In many parts of the industry need to surface temperature measurement, the measured surface temperature of the thermometer is what kind of? Instrument to solve for you: measuring surface temperature of the surface of the thermometer is now on the market thermometer, surface thermometer is to rely on the principle of the double metal induction principle of heat bilges cold shrink 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 following paragraph are surface thermometer, for your reference: ST200DM surface thermometer ST221SM surface thermometer thermometer ST221SS - ST221SS surface 3 surface surface thermometer is to rely on the principle of the double metal thermometer sensors principle of heat bilges cold shrink, 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.
