Work in Progress

Easy to Use

Easy-to-use, the EDG can be used as a construction aid to monitor day-to-day compaction operations by providing performance and measurement results highly comparable to those achieved with traditional methods, including the nuclear gauge and/or a sand-cone and oven moisture test combination.


When conducting a test, the EDG measures and displays the results for wet and dry density, gravimetric moisture content and percent compaction.
