ASTM D698 ASTM D1557 Portable Non-Nuclear Soil Density Gauge Moisture Meter Soil Compaction Tester

ASTM D698 ASTM D1557 Portable Non-Nuclear Soil Density Gauge Portable non-radioactive soil compaction tester for subgrade earthwork, serving as an alternative to nuclear density gauge and sand cone method. Principle of Operation Utilizes electromagnetic EDG technology. Four metal probes are inserted into soil to measure dielectric properties of the soil medium. Calculates wet density, dry density, moisture content and compaction ratio. Soil model calibration is required
