This manual describes how to use the 3430 density meter. The meter can measure the density, moisture content, and depth of concrete.
The Troxler 3430 Surface Moisture-Density Gauge is designed for measuring density and moisture in construction materials such as soil, asphalt, and concrete. The device operates in two primary modes: Soil mode for Proctor values and Asphalt mode for Marshall values. Users must prepare the test site carefully, ensuring the gauge rests on a smooth, level surface without rocking. Safety precautions, including wearing a dosimeter or radiation badge and safety glasses, are emphasized during operation.
