Model :FM-204TR
The FM-204TR Soil Hardness Tester measures soil penetration resistance to quickly determine dry density and compaction coefficient, using regression analysis and reference data tables based on the relationship between penetration, water content, and soil compactness.
Need Help with This Product?
The FM-204TR Soil Hardness Tester is designed for measuring soil penetration resistance, providing a quick and accurate way to determine soil density and compaction. Based on geotechnical principles, it establishes a correlation between penetration resistance, soil water content, and dry density through regression analysis and comparison with standardized data tables.
By measuring penetration resistance and referencing the provided data, users can easily calculate the dry density and compaction coefficient of soil. This makes the FM-204TR an essential tool for soil compaction testing in various geotechnical applications.
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.
