Classification and scope of use of moisture meters
The moisture analyzer of physical analysis method includes: infrared moisture analyzer, halogen moisture analyzer, microwave moisture analyzer, needle type, and induction type.
The infrared (halogen) moisture analyzer is simple to operate, requires less time, and has accurate measurement results. Therefore, the infrared moisture analyzer is widely used in all industries that require rapid moisture measurement, such as medicine, grain, feed, seeds, rapeseed, dehydrated vegetables, tobacco, chemical industry, tea, food, meat, and textiles, as well as in laboratories and production processes in industries such as agriculture, forestry, papermaking, rubber, plastics, and textiles. The microwave moisture analyzer uses a microwave field to dry samples, accelerating the drying process. It has the advantages of short measurement time, convenient operation, and high accuracy, and is suitable for moisture determination in petroleum, kerosene, and other liquid samples
The needle moisture meter uses the conductivity of the measured object to measure moisture. The higher the moisture content, the greater the corresponding conductivity. By measuring the conductivity of the measured object, the moisture value can be measured.
Inductive moisture meter is a type of microwave moisture meter. When the moisture content is high, the dielectric constant of the measured object increases, and the corresponding equivalent capacitance also increases. By measuring the equivalent capacitance of the measured object, the moisture value can be measured.
Rapid moisture analyzer [Instrument introduction]: The rapid moisture analyzer is designed based on the principle of pyrolysis weight and is a new type of rapid moisture detection instrument. The moisture meter measures the weight of the sample while the infrared heating unit and moisture evaporation channel quickly dry the sample. During the drying process, the moisture meter continuously measures and displays the lost moisture content% of the sample in real time. After the drying program is completed, the final measured moisture content value is locked and displayed. Compared with the international oven heating method, infrared heating can achieve maximum heating power in the shortest possible time, and the sample can be quickly dried at high temperatures. Its detection results are consistent with the national standard oven method, have substitutability, and the detection efficiency is much higher than the oven method. Generally, the sample can be determined in just a few minutes. The instrument is easy to operate and accurately tested. The display part uses a red digital tube, with clear and visible values. It can display data such as moisture value, sample initial value, final value, measurement time, temperature initial value, final value, etc. It also has the function of connecting with computers and printers.
This moisture meter can be widely used in all industries that require rapid measurement of moisture, such as pharmaceuticals, grains, feed, seeds, rapeseed, dehydrated vegetables, tobacco, chemicals, tea, food, meat, and textiles, as well as in laboratories and production processes in industries such as agriculture, forestry, papermaking, rubber, plastics, and textiles.
