The surface thermometer how to order

Surface thermometer is used in pipes, mold, chemical equipment, used to measure the surface temperature, special thermometer is pipes. 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 how to order? Instrument order thermometer on the surface of some parameters are summarized for you, for your reference: 1. Types, and the commonly used models have ST200DM, ST221SM, ST221SS etc. 2. Structure: single magnet, magnet, spring loaded; 3. Temperature range; 4. The precision requirement; 5. Material requirements; 6. Surface diameter; With these parameters, can convenient thermometer on the surface of the order. 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.
