The Nuclear Density/Moisture Tester (G852) is a portable, field-ready instrument used for rapid and accurate determination of in-situ soil and aggregate density and moisture content.
Utilizing gamma-ray attenuation and neutron scattering principles, the device provides real-time measurements of wet density, dry density, and moisture content, essential for quality control in earthworks and pavement construction.
The gauge operates in both direct transmission and backscatter modes, accommodating various material types and layer thicknesses, with a measurement depth range up to 12 inches (30 cm) in 1-inch (2.5 cm) increments.
Test durations are selectable via the control panel, offering options of 15 seconds, 1 minute, or 4 minutes, allowing flexibility between rapid assessments and high-precision measurements.
Equipped with a user-friendly interface and digital display, the instrument ensures straightforward operation and immediate access to test results, enhancing field productivity.
The G852 model incorporates safety features compliant with international radiation safety standards, including secure source encapsulation and shielding, ensuring operator protection during use.
