Surface thermometer, also known as magnet thermometer and pipeline thermometer, has the advantage of measuring temperature by magnet adsorption on the surface of the object to be measured, which is convenient to use
There are two main factors that affect the measurement accuracy of surface thermometer:
1. The magnet surface of the surface thermometer and the surface of the object to be measured must be wiped clean. If there is any impurity in the middle, it will cause the temperature loss, so that the measured temperature is not accurate.
2. The surface thermometer is conducted by magnet. Generally, the reaction time from placing to the surface of the measured object to the stable temperature display is about 15 minutes, that is to say, the reading must be accurate after 15 minutes
In addition, the surface thermometer should be cleaned and calibrated regularly, so as to ensure the accuracy of temperature measurement.
