Non-Nuclear Soil Electrical Density Gauge, Touch Screen, ASTM D 7830

The Electrical Density Gauge (EDG) is a nuclear-free alternative for determining the moisture and density of compacted soils used in road beds and foundations.

The EDG is a portable, battery-powered instrument capable of being used anywhere without the concerns and regulations associated with nuclear safety.

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.

  • Full color graphics driven user interface, touch screen operation.
  • New Status Bar feature, displays GPS status, data save status, available battery voltage, low battery status and date and time.
  • New data management feature, quickly Access, download, or delete your Project data.
  • Ability to download files from the device via USB drive.
  • Fast, reliable, accurate Material density and compaction test, and repeatable readings in real time, user friendly, cost effective.
  • No other method of calibration is required, and on-site testing can be performed directly. You can read the data accurately in three seconds, with higher precision and better stability.
  • Non-nuclear means no badges, licenses or storage and transport concerns.
