Audited Supplier SOIL HARDNESS TESTER
Model: FM-204TR
Application
This instrument is a special instrument for testing soil hardness. Compacting soil can prevent water infiltration, reduce the utilization rate of fertilizer, affect plant root growth, and even lead to crop yield reduction. Therefore, the compactness of soil is particularly important for guiding agricultural production, which can be a good guide to arable land and highway construction.
features Model: FM-204TR specifications
* High precision and high resolution.
* Numerical display, ignore the difference.
* N(Newton), kg(kg), lb(pound), g(gram) four measurement units are available for choice, mutual calculation.
* Peak hold function. Keep the peak display until manually cleared to zero.
* Can use alkaline battery power supply; It can also be connected to 5V DC power supply
Features
Universal type penetrometer is based on the geotechnical experiment: the penetration of soil and the dry density of soil, the relationship between the relationship between the penetration and water content of soil and the relationship
between soil water volume and compactness, through a lot of penetration and ring cutting parallel contrast test And establish
the regression equation, the rate of penetration resistance between the dry density and the related data sheet. By measuring the penetration resistance and looking up the table, the dry density can be quickly obtained, and then the compaction
coefficient can be quickly calculated. Two, main technical parameters
Principle
* It has no radiation, nuclear contamination, and is cheap, small and easy to carry in the field.
* It is used in domestic industrial and civil construction, highway, railway, road and bridge, municipal drainage, oil pipeline, water conservancy, dam construction, dike, irrigation canal, reservoir construction, airport runway engineering.
* Penetration method a group of tests up to 15-20 minutes, high efficiency, fast, productivity liberation.
