Description

Technical Field

[0001] The utility model relates to the field of thermometers, in particular to a high temperature resistant thermometer. Background Art

[0002] A thermometer is an instrument used to measure temperature. It is widely used in medical, industrial, food safety, environmental monitoring and other fields. It can accurately and quickly obtain the temperature information of the target object. In a granary, it is necessary to regularly measure the temperature of the grain at the bottom of the granary to prevent the temperature at the bottom from being too high and causing the grain to mold and deteriorate. Therefore, when measuring, it is generally necessary to frequently insert the barrel of the temperature measuring gun into the grain, so that the barrel needs to have certain wear resistance and high temperature resistance. Therefore, a high temperature resistant thermometer is proposed.

[0003] When the existing thermometers are used to measure the temperature of grain in a granary, the barrels of most temperature measuring guns are relatively short, so it is often necessary to find a suitable position before the barrel can be inserted for temperature measurement, which is relatively troublesome and takes a certain amount of time. In addition, the wear resistance and high temperature resistance of the existing temperature measuring gun barrels are relatively poor, and the temperature measuring gun barrels need to be frequently inserted into the grain, so that the grain rubs against the barrel of the temperature measuring gun for a long time, which can easily damage the barrel. Therefore, technical improvements are urgently needed. Utility Model Content
