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:

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.

A Nomograph function for density determinations in

asphalt layers of fewer than four inches.

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.

Over 30 functions to facilitate all phases of testing

compaction on construction materials.

A backlit LCD screen to help you read the display during

night construction.

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).

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
