Portable non-nuclear Asphalt EDG electrical density gauge

Model EDG-A Asphalt Pavement Quality Indicator utilizes advanced electromagnetic technology to obtain accurate asphalt pavement density readings. 

Features:

• no radioactive materials or special license required
• light weight and easy to use
• 24 hours of portable operation
• Measures density in common units (Kg./M3)
• Measures for asphalt temperature stores 4000 readings on internal data logger
• Optional download to computer 

Packing List

The density of asphalt pavement is directly proportional to the measured dielectric constant of the material. edg-a uses electrical waves to measure dielectric constant using an innovative, toroidal electrical sensing field established by the sensing plate. the electronics in the edg-a convert the field signals into material density readings and displays the results. Once calibrated, direct density readings can be consistently obtained. as shown below:

EDG-A can be used in three different measurement or run modes, respectively:

Single reading mode continuous reading mode        

Average reading mode 

Single reading time less than five (5) seconds.

Average averages five (5) readings and stores data including date and time.

stores thousands of records continuous instantaneous density readings. segregation identifies variations in material density associated with segregation.
