Density Gauges 3430 and 3440 Plus

Product Features

Troxler introduces the new and updated versions of the popular gauges which have been offered to customers for many years. The Model 3430 Plus and 3440 Plus gauges have been updated to offer more advanced electronics, updated software, and improved features. These gauges are used for compaction control of soil, aggregate, concrete, and full depth asphalt. These new devices were designed to be very similar to the current nuclear gauges that Troxler customers have become accustomed to, while offering many user-friendly features and some options which are brand new to the industry. Some of these new features and options include a larger display screen, measurement data storage in all gauges, a backlit LCD screen and automatic measurement data storage.

These two models appear very similar to each other, utilizing the same keypad and software, however the 3440 Plus offers many features never before seen on a nuclear gauge. These brand new features include: a remote start keypad, USB data transfer option, loud external beeper, and GPS capabilities (optional).

Meet ASTM Standards:
ASTM D-6938-06 (which replaced ASTM D-2922 and ASTM D-3017 as of November 2006), D-2950, and C-1040

 

Both the Model 3430 Plus & 3440 Plus gauges offer these features and capabilities:

Direct readout of wet density, dry density, moisture, % moisture, % voids, and % compaction

Powered by rechargeable NiMH batteries or backup alkaline batteries

Moisture, density, and trench offsets to adjust gauge measurements

Larger 4-line x 20-character display screen

Measurement data storage in all gauges

Backlit LCD screen

Automatic measurement record storage

Nomograph method for measurement of asphalt overlays

Forty years of Troxler experience and an extended eighteen month warranty give you the confidence you need in your field testing equipment

 

The Model 3440 Plus offers the same basic features as the Model 3430 Plus, but with these enhanced capabilities:

 

 

Remote start keypad on top of handle

USB port for data transfer via removable flash memory (“thumb” drive) or USB printer

Loud external beeper to indicate end of a count

Automatic indexing - Gauge senses the depth of the source rod automatically

Optional GPS (global positioning system) function - Reports latitude and longitude of measurement location at completion of reading

Backlit keypad for viewing in dimly lit jobsites

Notes:
Battery packs are fully protected against overcharge and over-discharge. Charge life is updated every 1.9 seconds and is indicated under the SETUP menu. Full NiMH recharge shall be made within 3 hours by means of a 110/220 V ac, 50-60 Hz charger. Recharging shall also be accomplished by a 12-14 V dc charger.

A fully charged battery will remain operational for approximately 3 weeks (of standard use) without the GPS option (available only on the Model 3440 Plus) or use of backlight options. These options will reduce the battery life when utilized. The alkaline backup batteries will add an additional 1.5 weeks when the GPS and backlight features are not operating.

The gauge can store up to 999 test readings for later recall or downloading to a printer or computer. The Model 3440 Plus gauge also allows for data transfer via a USB port utilizing a USB printer or a removable drive.
