In addition, there is an infrared moisture meter that uses physical heating to remove free moisture and measures moisture through weight changes. This type of moisture meter is often used in industries with low precision requirements, such as pharmaceuticals, plastics, chemicals, food, grains, etc. Because compared to an oven, the testing time is shorter, the use is convenient, the accuracy is higher, and the efficiency is much higher, usually only a few minutes.

A common moisture analyzer is the resistance method moisture analyzer, which places the test liquid sample in an electrolyte solution and generates an electric current through the contact between the electrode and the electrolyte in the solution. According to the different conductivity of the measured ions, the resistance value can be obtained separately, and then the conductivity of the measured liquid can be calculated based on the resistance value.
