CS830 neutron soil moisture meter is a variety of high-tech soil moisture content in one field measuring instruments. CS830 neutron soil moisture meter put the probe into the pre-laid a good conduit in the measurement, half a minute or so will be able to get a soil layer water content values. Do not sample the entire measurement process, accurate, fast, sounding not limited to, free from water physical state (eg, frozen) effects. CS830 neutron moisture gauge is mainly used for field measurement of soil moisture, observe the distribution of water stratification and dynamic changes, the crop water requirement studies, Water-saving irrigation guide. Frozen soil moisture products are used in cold regions and certain sectors of the long-term measurement of soil moisture data accumulation, etc. It can also be used for other material moisture measurement.

Neutron moisture gauge instrument uses single-chip computer system inside, directly show water content values, all calculations done automatically saved. It can be measured according to soil conditions input 10 polynomial calibration curves for calculation, and can freely call. Measurement results can be displayed or printed out, and can and computer on-line communication. The instrument is detected through the national health and epidemic prevention departments, radiological protection in line with national standards, it can ensure that the users health. This technology is the one of the internationally recognized measurement of soil moisture. Principle and application of mature technology has been widely used in agriculture, water conservancy, forestry, meteorology, geological engineering and many other fields, safe and convenient.

Neutron Moisture Meter Features:

1、Using small size probe, short source distance design, greatly enhanced measurement sensitivity and efficiency.

2、Work in the non-linear zone, polynomial fitting calculated to improve the measurement accuracy, expanded measurement range.

3、The use of low source strength of radioactive sources, security, good, equipment smaller and lighter.

4、A twenty-year service life for more than a high cost performance.

5、follow the latest progress of Computer technology and electronic technology, follow the developments in hardware and software and electronic circuit design of advanced, stable, low energy consumption.
