Electrical Density Gauge Model E - EDGe

Supports the following standards: AASHTO TP112

The EDGe provides Nuclear-Free, Field Density Measurements Based On In-Lab Proctor Test Data.

  • No Licenses
  • No Badges
  • No Hassles
  • Non-Nuclear Technology

Model E (EDGe) is used for determining the density and moisture content of aggregate, soil aggregate compacted type I or II base, or native soil materials that are suitable for shallow foundations, such as secondary roads or base aggregate that is compacted in-place prior to the asphalt or concrete placement at the final grade. The EDGe quality assurance / quality control (QA/QC) system is lightweight, easy to use, and nuclear free.

The lab unit provides you with the tools to take readings directly from your Proctor molds while performing the Proctor test. One Lab Unit supports multiple Field Units. The field unit is lightweight and comes in a rugged carrying case for easy transport and storage. You can expand your field capabilities by purchasing additional field units. Both units are nuclear free, which eliminates the need for radiation safety compliance regimens and transportation restrictions. The EDGe is simple to use.

EDGe Starter Unit Includes:

  • 1 lab unit - determining Proctor values
  • 1 field unit - on-site measurements

The advantages of using the EDGe are:

  • Complies with AASHTO T 399 and is an enhancement of ASTM D7698 that includes a laboratory aggregate calibration procedure
  • Nuclear-free device
  • Accurate and repeatable results that correlate to either ASTM D1557 or ASTM D698 standard Proctor tests
  • Does not require highly trained or licensed technicians
  • Does not require special handling for shipping or regulatory compliance for hazardous materials
  • Easy-to-learn and easy-to-use with its step-by-step menu
  • Lightweight and easily transportable
  • Eliminates costs associated with nuclear gauges

EDGe App

The EDGe App is available free from the Microsoft App Store. This app allows you to operate both the Lab and Field units of the EDGe, as well as provides the field unit with the lab Proctor data. In the field, the app will record dry density; wet density; percent moisture content; relative compaction; date; time, GPS coordinates and generate a location map. This data is routinely used for construction QA/QC certification reporting. The app can generate the reports in a PDF format, which can be saved or shared with others.

EDGe Software Features:

  • Download job data
  • Save and share customized reports in PDF format
  • Operate both the Lab and Field Unit
  • Provide the Field Unit with Proctor Data
  • Time/Date, GPS stamps for each test
  • Generate a location map
  • Computer/Tablet Required But Not Included

Recommended Computers:

  • Laboratory Use: Any Windows 10 Laptop or Tablet with Bluetooth® LE 4.0 or higher (e.g. MS Surface Pro or MS Surface Go 3)
  • Field Use: MS Surface Go 3 Tablet with Ruggedized Shell with Bluetooth® LE 4.0 or higher (recommended: Urban Armor Gear Shell & Screen Shield for Surface Go 3)
  • Microsoft compatible pen for laboratory and field use, optional mouse for laboratory use
  • A keyboard is recommended for laboratory use
