Nuclear Gauges for Density and Moisture

Nuclear Density Gauges

Nuclear gauges are one of the most accurate methods used to measure the moisture content and density of soils, aggregates, and other materials. These measurements are used for building roads and dams, and for collecting scientific data on soil water content in agricultural and forestry settings.

For a structure to stay in good condition, its soil and aggregate layers need to provide a stiff and stable foundation. A well-compacted base layer should be able to resist movement and deformation under stress. The density of in situ soils are therefore measured to ensure a structure’s performance and longevity meets industry standards.

A nuclear density gauge measures the density of in-place hot mix asphalt (HMA) using gamma radiation. Gamma rays are emitted from the source and interact with electrons in the material. By calculating the percentage of gamma rays returned to the source, the gauge can quickly and accurately measure the density and inner structure of the test material.

Humboldt’s nuclear density gauges are known to be less brittle and better equipped than the competition. Our gauges are built to last through years of rugged applications and are manufactured with 100% new parts. We take pride in the functionality and longevity our gauges have to offer.

Humboldt provides two nuclear density gauge models: the HS-5001SD and the HS-5001EZ.
