This new Gauge uses state-of-the-art technology to bring you a host of new features to make your job easier. Featuring a 4.3" touch-screen, the SD Gauge provides intuitive operation of all gauge operations. You also have the option to use the gauge's touch pad instead of the touch-screen, if desired.
The SD’s versatility allows it to measure density through direct transmission and backscatter modes, as well as including thin lift and trench modes, as well as moisture determinations. The gauge uses an advanced micro-processor-based technology to provide highly-accurate measurements of density and moisture that are automatically computed for direct readouts of wet density, dry density, moisture content, percent of moisture, percent of compaction (Proctor or Marshall), void ratio and air voids. The SD Gauge complies with all pertinent standards: ASTM D6938, D2950, C1040 and AASHTO T310.
