It takes a long time, so it is difficult to measure a large number of samples quickly. Therefore, for high-accuracy measurement on a variety of samples, other than an infrared moisture meter is not considered. Although there are some other electrical and optical measurement methods, they are all specialized instruments that limit the measurement object. In terms of versatility, they are far less than infrared moisture meters.
Scope of application: It can measure grains, starch, flour, dry noodles, brewed products, seafood, processed fish, edible meat products, seasonings, snacks, desserts, dairy products, dry foods, vegetable oils and other food-related items, medicines , ore sand, coke, glass raw materials, cement, chemical fertilizers, paper, pulp, cotton, various fibers and other industrial products.
3. Dew point moisture meter:
The dew point moisture meter 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 gases. However, this method has more interference, and some gases that are easy to be cooled and exchanged, especially when the concentration is high, will condense before water vapor and cause interference.
4. Microwave moisture meter:
The microwave moisture analyzer uses microwave field to dry samples, which accelerates the drying process. It has the characteristics of short measurement time, convenient operation, high accuracy and wide application range. It is suitable for granular, paper, wood, textile and chemical products. Moisture determination in powdery and viscous solid samples can also be applied to moisture determination in petroleum, kerosene and other liquid samples.
5. Coulomb moisture meter:
Coulomb moisture analyzers are often used to determine the moisture content in gases. This method is easy to operate and quick to respond, and is especially suitable for the determination of trace moisture in gas. It is very difficult to measure by a general chemical method. However, electrolysis is not suitable for the determination of alkaline substances or conjugated diolefins.
