Introduction to several types of moisture analyzers
Workers who have used a moisture analyzer know that a moisture analyzer is an instrument that can quickly and accurately detect moisture. Compared with the national standard method, the moisture analyzer takes less time and is more convenient to measure. At the same time, it can ensure the accuracy of the moisture test results and can be used in production and scientific research projects.
Moisture analyzers are distinguished from the measurement occasions, and there are three types: offline measurement, online measurement, and on-site measurement at any time. Off-line measurement, that is, laboratory sampling measurement, there are halogen moisture analyzers, infrared moisture analyzers, and Karl Fischer moisture analyzers; That is, an online moisture meter; an instrument that can be measured at any time on site, that is, a portable, hand-held moisture meter that can be carried around, such as a wall and floor moisture meter, a wood moisture meter, a textile raw material moisture meter, a paper carton moisture meter, and a portable moisture meter. Meat fast moisture meter and so on.
Moisture analyzers can be distinguished from the analysis methods. There are physical analysis methods, that is, physical heating methods to determine the moisture content, such as brine
Element moisture analyzer; another chemical analysis method, through the principle that the electrolyte reagent only reacts chemically with the water in the sample, it is very
Measure the moisture in the sample, such as Karl Fischer moisture analyzer (trace moisture analyzer).
Introduction of wood moisture tester
Microwave moisture measuring instrument (humidity meter) represents the new development of product moisture measurement technology. It adopts German measurement technology and can determine absolute moisture within 1 second. The accuracy of measurement results is high, and it is not affected by particles, colors and Any mineral effects. It is made by using the principle that microwave energy is attenuated by being absorbed when passing through a substance. It can be used to measure the moisture of coal powder, petroleum or various crops; check the humidity of grain depots; measure the moisture content of soil, fabrics, etc. For the production line conveyor belt control type, continuous non-contact online microwave measuring instruments can be installed. At this time, a pair of microwave antennas are installed on the measurement bracket on the production line. The transmitting antenna is installed under the belt, and the receiving antenna is installed on the belt. The density compensation measurement channel is installed before the microwave measurement channel, and the microwave rays pass through the material to be tested vertically.
