Features of the EZ-2 Gauge

FEATURES OF THE

EZ-2 Gauge

Humboldt’s HS-5001EZ-2 reflects the latest in portable, electronic design for nuclear gauges, featuring a large, back-lit LCD display. Humboldt’s EZ-2 Moisture/Density Gauge is just that — easy. Easy-to-operate, easy-to-power and easy-to-service. The EZ-2 Gauge features a menu-driven control panel with easy-to-use, built-in test routines and auto features, making testing a quick and accurate operation. It also features our innovative trigger release handle that eliminates pinched fingers while providing smooth operation.

The EZ-2’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 EZ-2 Gauge complies with all pertinent standards: ASTM D6938, D2950, C1040 and AASHTO T310, T355 and is calibrated by the Five-block calibration method ASTM D7013 and ASTM D7759.
