INTRODUCTION
Since 1958, Troxler has been the worldwide leader in precision
quality control and measurement equipment for the highway and
construction industry. Troxler’s Model 3430 and 3440 Surface
Moisture-Density Gauges have become the industry standard for
measuring the moisture content and density of construction
materials. With the Model 3430 Plus and 3440 Plus gauges, Troxler
has added a number of new 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 3430 Plus and 3440 Plus gauges, the operator can
quickly and precisely measure the moisture content and density of
construction materials. Both gauges feature:
♦
Two measurement modes (Soil and Asphalt) for precise
compaction control readings in most construction materials:
Soil Mode: For moisture/density determinations in soil and soil-
stone materials in layers of 4 inches or greater.
Asphalt Mode: For density determinations in asphalt or
hardened concrete layers of 4 inches or greater.
♦
A Nomograph function for density determinations in asphalt
layers of less than 4 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 liquid crystal display (LCD) to help the operator read
the display during night construction.
♦
Easy-to-use keypad and user-friendly menus to reduce training
time to increase productivity.
♦
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 the operator presses an invalid key, if the gauge
displays an error message, or to signal the conclusion of a
measurement.
