Humboldt H-4114SD.3F Electrical Density Gauge (EDG)
The Humboldt H-4114SD.3F EDG is a nuclear free portable gauge for measuring the density and moisture of compacted soils. It is an alternative to traditional methods such as the nuclear gauge and the sand cone test so crews can check compaction without radioactive source licensing, badges, or special transport rules. It is a battery powered, self contained unit in a carry case, and it is used for quality control on road bases, fills, and other compacted earthwork.
Key Features H-4114SD.3F EDG
- Nuclear-free testing: measures the electrical dielectric properties of the soil with no radioactive source
- Reports wet and dry density, gravimetric moisture content, and percent compaction: shown on the gauge after each test
- How it works: four darts are driven into the soil and the gauge makes point to point electrical measurements that are averaged then uses a soil model to turn them into physical results
- Soil models: a correlation between electrical signatures and measured physical data (from a standard test such as a Proctor) tailored to the material being tested
- Proctor data can be entered: maximum dry density and optimum moisture values are entered so the gauge can compute percent compaction
- Built-in GPS: records test location
- Self-contained and portable: the gauge, soil sensor, cables, and accessories are stored in the case and the unit is battery powered with a rechargeable lithium ion battery
- Temperature probe: the gauge uses temperature data to correct measurements
- USB port: for transferring data and updating the gauge firmware
- EDG Software: works with Microsoft Excel to communicate with your gauges upload soil models to any EDG and manage results
- Accuracy: Humboldt states dry density accuracy within about 3% of standard tests
- Kit contents: the console and case four tapered 6 inch darts, a hammer, and the soil sensor and cables with a calibration device matched to the gauge serial number
- Dart options: 4, 6, 8, 10, and 12 inch darts are available separately for different test depths (four are needed per test)
Typical Applications H-4114SD.3F EDG
- Compaction testing of road bases, subgrades, and embankments
- Quality control and acceptance testing on earthwork projects
- Sites where nuclear gauge licensing or transport is a burden
- Developing and applying project specific soil models
Why Choose It
The H-4114SD.3F EDGÂ gives contractors and testing labs a way to measure density and moisture on site without the regulatory overhead of a nuclear gauge. Built in GPS and software support make it straightforward to log and report tests.
