The thermometer containing magnetic? Instrument answer: the thermometer on the market now is a lot of more phyletic, the surface thermometer containing magnetic, with magnets, so also known as magnet thermometer. Magnet principle is to rely on bimetallic thermometer sensors principle of heat bilges cold shrink, measured by contact thermometer at the bottom of the magnets to metal surface and reading. This type of double metal surface thermometer can range from - 40 c to 500 c, the accuracy can be for the use of some of the requirements for accuracy is not too high, can yet be regarded as a money and cheap beautiful surface thermometer thermometer commonly used on the pipeline, chemical industry equipment, used to measure the surface temperature, special thermometer is pipes. Surface 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.
