Explanation of different classifications of moisture meters. Moisture analysis methods can generally be divided into two main categories: physical analysis and chemical analysis. This article introduces several classic methods for moisture analysis. Traditional moisture analysis methods have gradually been replaced by various other approaches. The main types of moisture meters available on the market include Karl Fischer moisture meters, Coulomb moisture meters, microwave moisture meters, infrared moisture meters, dew point moisture meters, as well as some specialized moisture meters. These instrument measurement methods are easy to operate, highly sensitive, have good reproducibility, enable continuous measurement, and automatically display data. Coulomb moisture meters are commonly used to measure the moisture content in gases. This method is easy to operate and responds quickly, making it particularly suitable for determining trace amounts of moisture in gases. If measured using ordinary chemical methods, it is an extremely difficult task. However, the electrolytic method is not suitable for the determination of alkaline substances or conjugated dienes. Microwave moisture meters use microwave fields to dry samples; Millipore Di accelerates this drying process. They feature short measurement times, easy operation, high accuracy, and a wide range of applications. They are suitable for determining moisture content in granular, powdered, and viscous solid samples such as those found in grains, papermaking, timber, textiles, and chemical products. They can also be used to measure moisture content in petroleum, kerosene, and other liquid samples. Infrared moisture meters are easy to operate, require little time, and provide accurate measurement results; therefore, they can be widely used in industries such as chemicals, pharmaceuticals, food, tobacco, and grains for experimental analysis, as well as for daily quality control and process monitoring. The dew point moisture meter is easy to operate; it is not complex, and its measurement results are generally satisfactory. It is commonly used for detecting trace amounts of moisture in gases. However, this method causes a lot of interference; some gases that are prone to condensation will, especially at higher concentrations, condense before water vapor, thereby causing interference. The Karl Fischer method is a classic technique; improvements made in recent years have enhanced its accuracy and expanded its measurement range, and it has been established as the standard method for determining moisture content in many substances.
