SR-4500

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.

Features
· It does not require a highly-trained or licensed technician;
· It does not require special handling for shipping or regulatory compliance for hazardous materials;
· It is easy to learn and easy to use with its step-by-step menu;
· Lightweight and easily transportable;
· It is accurate and repeatable with results that mirror known testing methods.

Software
The software will allow you to communicate effortlessly with your EDG gauges and only requires minimal setup by the user. EDG Software provides a complete solution for the acquisition, storing, and presentation of Job and Soil Model data. EDG Software works in conjunction with Microsoft Excel to present test data in easy-to-read Excel workbook format files, which can be evaluated directly or sent to any computer using Microsoft Excel. Jobs can be grouped together within projects for organization and reporting.

Software features
· Communicate with all your EDG gauges.
· Download Job Data.
· Create customized reports from downloaded job data.
· Download Soil Model Data.
· Create reports from downloaded soil model data.
· Upload soil models to any EDG.
