NUCLEAR DENSITY GAUGE MODELS

Moisture/Density Gauges
These are the commonly used Troxler gauges that we sell, service, and calibrate:
  • 3430P Basic Moisture/Density Gauge
  • 3440P Advanced Moisture/Density Gauge
  • 3450 Combination Moisture/Density/Thin Layer Gauge
    (This is the most versatile model.)
  • 4640B Thin Layer Gauge
    specifically designed for thin asphalt layers

TROXLER 3430 Plus

The 3430 Plus is the most basic general purpose gauge.
​
The 3440 Plus is the more highly featured of the two and the most popular in New Zealand.
The main differences between the 3430 and a 3440 are:
  • The 3440 can store data to download later into a computer.
  • The 3440 has a more sophisticated display.
  • There is no depth indicator on a 3430. (This is of little consequence if you are doing mainly backscatter measurements).

TROXLER 3440 Plus

Troxler 3440 is the most widely used model in New Zealand and has now been upgraded to the 3440 Plus.

Note that the general purpose Moisture/Density gauges like the 3440 and 3430 are calibrated for soil, not asphalt. They are accurate on thin layers only if the user knows the density of underlying layers.

Accessories, Features, and Specifications
A 3440 Plus is supplied with standard accessories, as shown, including:
  • Calibration Certificate
  • instruction manual
  • carry case
  • scraper plate
  • drill rod
  • extraction tool
  • plastic reference block
  • charger

3440 Plus Features and Benefits

Direct readout of:
  • Wet density
  • Dry density
  • Moisture
  • % Moisture
  • % Compaction
  • % Voids
(The older 3440 did not read % voids.)

Easier to use - with less bending for the operators.
  • Remote start keypad on top of handle.
  • Larger display screen: 4 lines x 20 characters.

More features of the new Troxler 3440 Plus
  • Back-lit LCD screen and
  • Back-lit keypad:
  • for viewing in dimly lit job sites or for night work.
  • USB port:
  • for data transfer via removable flash memory ("thumb"-drive) or USB printer
​Also:
  • Improved automatic indexing:
  • The gauge senses the depth of the source rod automatically
  • Automatic storage or measurement records
  • Loud external beeper to indicate end of a count
  • Powered by recharchable NiMH batteries or backup alcaline batteries
  • Optional: GPS (Global Positioning System)
  • Reports the latitude and longitude of the measurement location at completition of reading

TROXLER 4640B

Thin-Layer Gauge 4640B
The Thin-Layer gauge is particularly designed for thin asphalt layers, and does not need to know the density of underlying material to be able to measure density..
