The Model 3440 Surface Moisture-Density Gauges have become
the industry standard for measuring the moisture content and
density of construction materials. With the new Model 3440
gauge, Troxler has added a number of features to the proven
technology of the company’s earlier products to provide
increased performance, flexibility, ease of use, and operator
safety.
Using the Model 3440 gauge, you can quickly and precisely
measure the moisture content and density of construction
materials. The gauge features:
i Two measurement modes (Soil and Asphalt) for precise
compaction control readings in most construction materials:
Use Soil Mode for moisture/density determinations in soil
and soil-stone materials in layers of four inches or greater.
Use Asphalt Mode for density determinations in asphalt or
hardened concrete layers of four inches or greater.
i A Nomograph function for density determinations in
asphalt layers of fewer than four inches.
i Calibration offsets (density, moisture, and trench) to
expand measurement possibilities, and to enhance gauge
readings on materials that may fall outside the range of
factory calibration.
i Over 30 functions to facilitate all phases of testing
compaction on construction materials.
i A backlit LCD screen to help you read the display during
night construction.
i Easy-to-use keypad and user-friendly menus to reduce
training time to increase productivity. A backlit keypad is
available as an upgrade (see page 5–17 for more
information).
i An internally mounted beeper, which emits a short tone in
response to a valid keystroke on the keypad. The beeper
sounds a longer tone if you press an invalid key, if the gauge
