Fast grain moisture tester

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.

Common weightlessness water meter has halogen water determination, infrared water meter, microwave water meter and so on;
Common Carl Fisher water meter mainly include capacity method Carl Fisher water meter and Coulomb method (power method) Carl Fisher water meter.

Based on research and development of natural latex moisture meter, metrology institute of hunan province proposed to determine the standard value, peng to calibrate instruments, after verification, found that ethanol is a good linear calibration substances, ethanol based on linear calibration substances, metrology institute development research, together with the Hersey instrument equipment provided by hunan Hersey instrument prototype machines and database software. Hunan Provincial Institute of Metrology provides measurement transfer and calibration, with the fastest speed to enable us to jointly complete the calibration standard machine of natural latex water content, ethanol water content tester, to solve the problem of natural latex water content calibration and traceability for many years.

In the context of the COVID-19 outbreak, the project of redeveloping special ethanol water content tester with standard machine was proposed by Xunjiyong of Hunan Husi Instrument for novel Coronavirus prevention.

In early 2020, hunan Husi Instrument drafted the team standard of China's export and import quarantine agreement. In October 2020, the determination method of ethanol water content was "Rapid determination of ethanol water content by microwave transmission method" T/CIQA 7-2020 ".

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.

Hunan Hexi Instrument Equipment Co., Ltd. was established in Xiangjiang New Area in 2007. After more than ten years of development, it has become a high-tech enterprise integrating r&d, production and sales of laboratory instruments and equipment with independent intellectual property rights, independent brand and independent innovation ability.
