The instrument that can detect the water content of all kinds of organic and inorganic solids, liquids, gases and other samples is called the water meter, and the physical meter and chemical measurement method can be classified according to the determination principle.Physical determination method is commonly used in weightlessness method, distillation stratification method, gas chromatography analysis method, etc., the chemical measurement method mainly includes Carl Fisher method (Karl Fischer), toluene method, etc., the International Organization for Standardization set Carl Fisher (Karl Fischer) method as the international standard for trace water measurement, our country also set this method as the national standard for trace water measurement.
Hydrometer method: it takes more than 48 hours for a single measurement. The equipment is too large to be portable.
Gas chromatography: cumbersome equipment configuration, the need to use professional chromatographic columns, high requirements for operators, expensive, not portable.
Volume density method: expensive equipment, high requirements for the site, not portable.
Microwave transmission method: the equipment is affordable, accurate measurement, small size, portable, on-site detection.
Characteristics of microwave water meter:
The rapid water portion meter is a fast and intelligent measurement of the water content in a specific substance, with a single measurement time to digitize the specific material content within 2-3 seconds.
This instrument uses the water molecules and solid forms in specific substances to measure the different reactions of the microwave at different temperatures, and uses the computer to obtain the correct measurement results.
The instrument uses a computer to control the waveguide oscillator to radiate a fixed frequency, fixed strength and match the tested sample.
The instrument uses an automatic feeder to send the specific material to be determined into the measurement tube, minimizing the uncertainty error caused by manual operation.
Rapid water meter uses advanced digital technology to visually show the correct measurement results.
The microwave moisture meter measurement automatically recovers the specific material to minimize the waste of raw materials.
