Types and Applications of Moisture Analyzers
With the development of scientific research and the advancement of production technology, quantitative analysis of moisture has been listed as one of the basic items for physical and chemical analysis of various substances, and as an important quality indicator for various substances.
Different requirements for measuring moisture were proposed based on the varying moisture contents in different forms of samples. Moisture measurement can be used for control analysis in industrial production or for quality assurance of agricultural and industrial products; Moisture can be determined from products measured in tons or analyzed in the laboratory using only a few microliters of the test solution; It can be a constant moisture analysis with a moisture content of several percent to tens of percent, or a trace moisture analysis with a moisture content of less than one millionth, and so on.
These instrument measurement methods are easy to operate, have high sensitivity, good reproducibility, and can continuously measure and automatically display data. Foreign moisture meters are expensive, which some domestic laboratories and enterprises cannot afford. In recent years, many domestic instrument manufacturers have strengthened their research and practice on moisture meters, achieving significant benefits and bringing the various technologies of domestic moisture meters closer to international standards, which can meet the needs of general laboratories and enterprise production. The classic moisture analysis method has gradually been replaced by various moisture analysis methods.
The rapid moisture analyzer, designed based on the principle of thermogravimetric analysis, is a new type of rapid moisture detection instrument. The moisture analyzer 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 analyzer continuously measures and displays the percentage of lost moisture in 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 reach the maximum heating power in the shortest time, and the sample can be quickly dried at high temperatures. Its detection results have good consistency with the national standard oven method, are replaceable, and the detection efficiency is much higher than that of the oven method. Generally, the sample can be measured in just a few minutes. The instrument is easy to operate and accurate in testing. The display part uses a red digital tube with clear and visible readings, which 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.
