Overview
Hanxian type soil moisture meter
Product Details
Instrument name:Soil moisture tester
model:SU-LB
Instrument testing principle:
Adopting the most popular on-site testing principle for soil moisture internationally: Frequency Domain Reflectance (FDR) principle, the sensor emits electromagnetic waves of a certain frequency, which are transmitted along the probe and return to the bottom to detect the output voltage of the probe. As the change in soil dielectric constant usually depends on the soil moisture content, the soil moisture content can be calculated from the relationship between the output voltage and moisture. Moisture is the main factor determining the dielectric constant of soil. Measuring the dielectric constant of soil can directly and stably reflect the true moisture content of various soils. The FDR soil moisture sensor can measure the volume percentage of soil moisture, which is independent of the mechanism of the soil itself. This principle is currently the most popular soil moisture sensor measurement method internationally.
Application scope of the instrument: agriculture, forestry, environmental protection, water conservancy, and meteorological industries.
Main functional features of the instrument:Large screen LCD Chinese character display operation process, user-friendly menu.
The sensor support material is epoxy resin, ensuring strength and lifespan.
Good sealing performance, can be buried in soil for a long time, and is not corroded.
The use of standard current loop transmission technology gives it strong anti-interference ability, long transmission distance, and remote control testing, with a maximum distance of up to 1000 meters.
High measurement accuracy and fast response speed (1 second).
The impact of soil quality is relatively small, the application area is wide, the price is low, and it is suitable for China's national conditions.
Fast testing speed, results can be obtained in just 5 seconds.
Adopting imported digital circuits, programmed control, and large screen LCD Chinese character display. Convenient and intuitive.
Handheld structural design, easy to carry, sturdy and durable.
The unique built-in charging circuit and battery pack have a charging life of over 2000 times. Easy to use and highly reliable.
Function can be extended to include moisture, temperature, soil hardness, soil compaction, etc. (not standard)
