Overview
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 that 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.
Meet ASTM Standards:
ASTM D-6938-06 (replaced ASTM D-2922 and ASTM D-3017 as of November 2006), D-2950, and C-1040
Features & Benefits
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
- Extended 18-month warranty
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 or USB printer
- Loud external beeper to indicate end of a count
- Automatic indexing: the 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
