EZ Gauge Features

Humboldt’s HS-5001EZ Moisture/Density Gauge is just that — easy. Easy to operate, easy to power and easy to service. The EZ 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’s versatility allows it to measure density through direct transmission and backscatter modes, as well as thin lift, trench modes and 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 Gauge complies with all pertinent standards: ASTM D6938, D2950, C1040 and AASHTO T310 and is calibrated by the Five-block calibration method.

Easy Self Repairs

The EZ gauge also uses a modular design, which allows it to be serviced in the field, if ever necessary. With this gauge, you don’t have to send it back to the factory for repairs – we’ll send you the necessary components and walk you through many of the repair procedures.

Easy to Power

The EZ is powered by six standard AA alkaline batteries, which provide up to 1400 hrs of service. No chargers are needed and you can buy batteries almost anywhere, including the corner convenience store.
