Product ID: Model 3440
 
The Model 3440 gives you the features you need for compaction control, but its enhanced capabilities make it a step above our basic Model 3430. The Model 3440 is used to measure the density of asphalt, soil, aggregate or concrete and the moisture of soil or aggregate.

Product Details

Height: 18,3 cm (7,2 in.)
Width: 37,6 cm (14,8 in.)
Depth: 23,1 cm (9,1 in.)

Further Description

Density can be measured in either the backscatter or direct transmission mode and moisture is measured in the backscatter mode. The backscatter mode is ideal for concrete and hot asphalt, while direct transmission is the choice for 50 - 300 mm (2 - 12 inch) lifts of soil and aggregates. Test results in as little as 1 minute allow additional compactive effort to be applied immediately if necessary. The Model 3440 and all other gauges in the 3400 series have replaced conventional density test methods and have become the industry standard. It also meets ASTM Standard Test Methods D-2922 and D-3017.

The Model 3440 gives you the same basic features as the Model 3430, but with these enhanced capabilites:

  • Storage of up to 450 tests eliminates the need to manually record results  
  • All stored test results are retained in user selectable projects for easy retrieval  
  • Identification of stored test results by station number and distance left or right of centerline reduces the possibility of misreporting results  
  • Advanced data management using the RoadReader Data Management System (DMS) allows downloading of results to a computer where multiple projects can be combined, data can be edited and customized reports can be prepared
  • Automatic depth setting eliminates the possibility of manually entering an incorrect depth  
  • Special calibration and trench, moisture and density offsets let you adjust the gauge to virtually any field condition  
  • Forty years of Troxler experience and an extended eighteen month warranty give you the confidence you need in your field testing equipment.
