Description

Technical Field

[0001] The utility model relates to the technical field of detection instruments, in particular to a moisture meter which is easy to clean. Background Art

[0002] An instrument that can detect the water content in various organic and inorganic solids, liquids, gases and other samples is called a moisture meter. According to the measurement principle, it can be classified into two categories: physical measurement method and chemical measurement method. Commonly used physical measurement methods include weight loss method, distillation stratification method, gas chromatography analysis method, etc., and chemical measurement methods mainly include Karl Fischer method, toluene method, etc. The International Organization for Standardization has set the Karl Fischer method as the international standard for measuring trace moisture, and our country has also set this method as the national standard for measuring trace moisture.

[0003] At present, when the existing moisture meter detects the material, it is necessary to use a heater to heat the material tray and the material. After the detection, the material tray needs to be cleaned manually in time to prevent the material from adhering to the inner wall of the material tray. Since the temperature at which the heater heats the material tray and the material is too high, the operator is easily scalded when cleaning the material tray, which makes the cleaning of the material tray more inconvenient.
