Troxler 3430 Nuclear Density Gauge
The Model 3430 provides the basic features required for determining the density of asphalt, soil, aggregate or concrete and the moisture of soil or aggregate.
It and the other gauges in the 3400 series have replaced conventional density test methods and have become the industry standard.
The Model 3430 offers you a choice of backscatter or direct transmission for density measurement and backscatter for moisture measurement.
The Model 3430 adheres to ASTM Standard Test Methods D-6938 (which replaced ASTM D-2922 and ASTM D-3017 as of November 2006), D-2950, C-1040 and AASHTO T-310.
The gauge directly displays wet density, moisture, dry density, percent moisture, percent compaction, void ratio and percent voids in English or metric units.
