Electrical Density Gauge

Soil Compaction Testing Equipment

Electrical density gauge (also referred to as EDG) is utilized for measurement of field compaction of soil. EDG is nuclear-free alternative for determining the moisture and density of compacted soils used in road beds, foundations & construction sites. The instrument provides an output and graph based on soil model for the site of compaction%, moisture%, wet & dry density.

The advantages of using the Electrical Density Gauge are:

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


Product Specification
Measures : Wet Density in g/cm³, Dry Density in g/cm³, Moisture % Compaction
Display : Touchscreen color display
Conforming to ASTM D7698
Data Storage Upto 2,000 projects of 2,000 tests
Supply Includes EDG instrument, battery charger, GPS, Dart template, 6” Darts - 4 Nos, Hammer carry Case
  • Computerized instrument that is menu driven for guiding on step by step measurement
  • EDG is also relatively quicker than Nuclear density gauges
  • Instrument provides indirect measurement of field compaction
  • Soil model can be developed easily at site
  • Reference reading from traditional method such as cone replacement or from nuclear gauge is sufficient for generating soil model.
  • GPS data can be integrated into test results
  • In-situ temperature measurement is recorded

How To Choose An Ultrasonic Thickness Gauge -Part II
The decision on whether you need to measure  : 1. Thickness of sheet metal 2. Evaluate the onset of corrosion in metal fabricated structures 3. Thickness of small diameter pipes such as boiler tubes, automotive pipes etc amongst others, will decide which thickness gauge instrument you should purchase to satisfy the application. A thickness gauge is an investment in quality production of components, to test quality of product purchased and finally to ensure a higher lifetime of asset by identifying corrosion. Purchasing a world class quality  instrument such as Dakota ultrasonic thickness gauge ensures that your teams are utilizing product which will provide consistency and repeatability in measurements ensuring that the process of quality assurance or quality testing can be inducted into your organization as a process and not as a daunting task. Many a times questions are asked – give us an ultrasonic thickness gauge instrument which is easy to use ...
How To Choose A Material Thickness Gauge - Part I
Thickness gauges are utilized where a micrometer or vernier caliper cannot be utilized – for measuring thickness of large sheets of metal or other substrates which can otherwise not be measured using the above devices. [caption id="attachment_54" align="alignleft" width="150"] Ultrasonic Material Thickness Gauge[/caption] A thickness gauge works on the principle of ultrasonics, i.e a signal is sent into the substrate through the transmitter  of an ultrasonic transducer which when received allows the thickness of the substrate to be measured. While all this sounds so simple, should all ultrasonic thickness gauges not be the same?  Which leads to the questions – 1.  what is the type of substrate under test ? egg, steel, aluminum, iron, titanium, glass etc. 2.  What are the conditions in which the thickness gauge will be used, will there be dust, oil, water ? 3.  Is it a simple sheet of material or a final product ? 4. How thin or ...
