Humboldt HS-5001NX Nuclear Gauge

Features of the NX Gauge

FEATURES OF THE

NX Gauge

Humboldt’s New HS-5001NX Moisture/Density Gauge provides more efficient operation, data collection and processing than any other gauge in its class. The HS-5001NX brings you a host of new features aimed at making your job easier. Featuring a color touchscreen, the NX Gauge provides intuitive operation of all gauge operations. It also provides touch pad operation as an alternative control method.

The New NX's versatility allows it to measure density through direct transmission, backscatter, thin lift and trench modes, as well as providing moisture determinations. The gauge uses an advanced microprocessor-based technology to provide highly accurate measurements of density and moisture that are automatically computed for direct readouts of wet density, dry density, moisture content, percent of moisture, percent of compaction (Proctor or Marshall), void ratio and air voids.

The New NX Gauge complies with all pertinent standards: ASTM D6938, D2950, C1040 and AASHTO T310, T355 and all other international standards. The gauge is calibrated by the Five-block calibration method ASTM D7013, D7759.
