Troxler Nuclear Density Meters (NDM)

NZS 4407.4.2:2015 | NZS 4407.4.3:2015 | NZS 2891.14.1.1:2013 | NZS 2891.14.1.2:2013 | NZS 2891.14.2:2013
These are the popular nuclear density meters from Troxler that we sell, service, and calibrate:
  • 3430+ RoadReader Basic Moisture Density Gauge
  • 3440+ RoadReader Advanced Moisture Density Gauge
  • 4640-B Surface Thin Layer Density Gauge

RoadReader Model 3430 & 3440 Moisture Density Gauges

3430
The Model 3430 is the simplest and most economical gauge offered by Troxler.

This gauge offers many features, including:
  • Improved operation and reliability with updated electronics
  • Fast recharge with NiMH batteries
  • Easier to read in all lighting situations with an enlarged backlit display screen - 8mm characters

Optional features for the Model 3430 include:
  • Remote start keypad near the handle
  • Alkaline batteries for backup use
  • External beeper
  • Software, keypad, and manual in Spanish and French
  • Data storage
  • USB port
3440
The Model 3440 is for users who want user-friendly features.

Along with the standard features provided in the Model 3430, the Model 3440 provides additional features including:
  • Automatic depth function
  • USB port for data transfer
  • Data storage (1000 readings)
  • Alkaline battery backup

Optional features offered for the Model 3440 include:
  • GPS location
  • Remote start keypad near the handle
  • Backlit keypad
  • External beeper
  • Software, keypad, and manual in Spanish and French
Both models offer:
  • Density measurement capability in backscatter or direct transmission mode
  • Moisture measurement in backscatter mode to allow quick, non-destructive testing of soil, asphalt and concrete materials
  • Direct readout of test results (wet density, dry density, moisture, % moisture, % voids, and % compaction)
  • Multiple count time options (15 seconds, 1 minute, 4 minutes)
  • User-friendly menus and keypads
  • Options of 12”/2”, 12”/1” and 8”/2” depth measurement capability

The gauges meet or exceed the ASTM standards D6938, D2950, and C1040.

4640-B Surface Thin Layer Density Gauge

4640-B
Recognizing the need for an improved method of measuring the density of thin layer asphalt overlays, Troxler developed the first true thin layer density gauge, the 4640-B Surface Thin Layer Density Gauge.

Designed to measure the density of thin asphalt and concrete layers from 2.5 to 10 cm
(1 - 4 inches), the Troxler Model 4640-B Thin Layer Density Gauge accurately measures the overlay density without influence from underlying material. No nomographs or manual corrections are required in order to compute the true density of the overlay. With onsite results available in as little as one minute, the Model 4640-B can provide the user with test results when they are needed, not hours after compaction has been completed.

Special Functions:
  • Automatic standard count comparison and storage
  • Data storage of 750 records for later viewing, printing, and/or downloading
  • Determination of the count time for selected precision
  • Field offsets of density and a special calibration function
  • Calculator mode
  • Diagnostics and self-test modes
  • Simple data transfer to a portable device using the free Troxler App

The Troxler Model 4640-B Thin Layer Density Gauge complies with ASTM D2950 and AASHTO T 355.

PaveTracker™ Model 2701-B Plus Non-Nuclear Gauge

Picture
The PaveTracker™ Model 2701-B Plus is an electromagnetic density indication device for asphalt quality control measurements.

This gauge contains no radioactive material, so no licensing or special training is required to own or operate this equipment. Your entire asphalt paving team could be ready to perform asphalt quality control measurements at a moment’s notice.

The PaveTracker™ Model 2701-B Plus weighs only 5 kg, and it displays measurement results in only two seconds. This allows the user to measure larger areas in a shorter amount of time. If problem areas are found, further compaction effort can quickly be made to increase the density of the asphalt. Areas of segregation, low density, and/or other non-uniformity are easily detected by the PaveTracker, which allows the
operator to resolve issues before construction completes.


There is no need to enter potentially inaccurate corrections for moisture and temperature.
Standard Features:
  • Reference test plate built into the case allowing the operator to test the unit as often as desired
  • Two handles are standard - detachable longer L shaped handle and an attached bail handle
  • Large backlit display and keypad can be easily seen from a standing position and in dim light
  • Self-adhesive protective sensor cover disc is easily replaceable in the field
Optional Features:
  • Infrared Temperature Sensor measures and displays the mat temperature.
  • GPS location capability reports latitutde and longitude with each measurement result.

The PaveTracker™ Model 2701-B Plus complies with ASTM D7113 and AASHTO T 343.
