Introducing Humboldt’s next generation, Non-Nuclear, soil density, field and in-lab gauge, the EDGe (model e). The EDGe provides Nuclear-Free, Field Density Measurements Based On In-Lab Proctor Test Data.

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

Now you can retire your nuclear density gauge and replace it with the innovative, Proctor-driven EDGe! It's your easy Lab-to-Field solution!

Humboldt‘s Non-Nuclear, Electrical Density Gauge, Model E (EDGe) is a nuclear-free alternative for determining the moisture and density of compacted soils.

The new EDGe will determine 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.

Humboldt's EDGe Starter Unit Includes:

• 1 unit for the lab
• 1 unit for the field

EDGe Lab Unit

The laboratory aggregate calibration procedure involves electrical testing of a representative sample of the construction aggregate or soil materials while performing either an ASTM D1557 Standard Test Method for Laboratory Compaction using a Modified Effort of 56,000 ft-lbf/cubic foot or the ASTM D698 Standard Test Method for Laboratory Compaction using a Standard Effort of 12,000 ft-lbf/cubic. During the laboratory test, the EDGe lab-sensor and a Windows 10 laptop or computer are used to collect and manage the physical and electrical data during the Proctor test. The software generates a Proctor curve that displays the maximum dry density at the calculated optimum moisture content and is saved and typically printed for client reports. The empirically derived correlations relate the electrical and physical properties of the aggregate or soil that is scheduled for placement and compaction on construction project sites, such as road construction or other shallow foundation. The physical and electrical data from the Proctor test is saved on the laboratory laptop computer. This data can then be transferred to the ruggedized field Windows 10 tablet by USB stick, a cloud service, or wirelessly, for use with the EDGe field equipment for quality assurance / quality control (QA/QC) testing and construction quality certification.

EDGe Field Unit

The EDGe field unit is a portable, battery-powered instrument capable of being used anywhere without the concerns and regulations associated with nuclear safety. It uses a lightweight, ruggedized backpack for easy transport and storage. Just grab the backpack and you're off to your testing site.

During the field quality assurance / quality control testing, the EDGe field-sensor and a ruggedized Windows 10 tablet or computer manages the project data. The EDGe field hardware is used along with the EDGe field sensor and the tablet to test the density and moisture of the construction materials. In the field, the EDGe measures the electrical properties of the aggregate and calculates physical properties by utilizing the established relationship of the electrical and physical characteristics from the laboratory aggregate calibration procedure Proctor test. Field tests take a few minutes to perform, and the material field properties are displayed in real-time, as well as being saved for report printing. The EDGe field reports provide the user and client with quality assurance / quality control data that includes the compacted material dry density, wet density, the percent moisture content, relative compaction, date, time, and GPS coordinates and a location map. The client reports can include additional project information such as the project name and number, the EDGe field sensor unique identification number, the EDGe operator’s name, the company name, and other information in the remarks section, such weather conditions, if needed.

The EDGe App

The EDGe App, 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 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
