TransTech Systems has announced its new Model SDG Soil Density Gauge. Similar to the company’s PQI Asphalt Density Gauge, the new device brings non-nuclear, impedance-based density and moisture measurements to soil applications. The SDG, says TransTech, is quick to set up, captures data in seconds and is suitable for soil compaction jobs, such as sub-bases, embankments, fills, foundations, dams, landfills and utility cuts.
