About the classification of moisture analyzer

Water analysis methods can generally be divided into two major categories, namely physical analysis and chemical analysis. The classic moisture analysis method has been gradually replaced by various moisture analysis methods. Currently, the main moisture analyzers on the market include Karl Fischer moisture analyzer, infrared moisture meter, dew point moisture meter, microwave moisture meter, and Coulomb moisture meter. And some special moisture meter - coal moisture analyzer - automatic moisture analyzer (light moisture analyzer). These instruments are simple, sensitive, and reproducible. They can measure continuously and automatically display data.

The Karl Fischer method is a classical method. After improvements in recent years, it has greatly improved the accuracy and expanded the measurement range. It has been listed as a standard method for moisture determination in many substances.

The infrared moisture analyzer is simple in operation, less time-consuming, and accurate in measurement results. Therefore, the infrared moisture meter can be widely used in laboratory analysis, daily stock control, and process detection in chemical, pharmaceutical, food, tobacco, food, and other industries.

The dew-point moisture analyzer is easy to operate, the instrument is not complicated, and the measured results are generally satisfactory. It is often used for the determination of trace moisture in permanent gas. However, this method interferes more. Some cold-changeable gases, especially at higher concentrations, interfere with condensation than water vapor.

Coulomb moisture meters are often used to determine the moisture content of gases. This method is easy to operate, quick to respond, and especially suitable for the determination of trace moisture in gases. If you use ordinary chemical methods, it is very difficult. However, electrolytic methods are not suitable for the determination of alkaline substances or conjugated diolefins.

Coal Moisture Analyzer--Microwave Moisture Analyzer uses microwave field to dry samples. The milliporesdi accelerates the drying process. It has the characteristics of short measurement time, convenient operation, high accuracy and wide application range. It is applicable to food, paper, wood, textiles and The determination of moisture in granular, powdery, and viscous solid samples such as chemical products can also be applied to the determination of moisture in petroleum, kerosene, and other liquid samples.
