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 gauge provides a single gauge solution to density and moisture measurements.
The EZ’s versatility allows it to measure density through direct transmission and backscatter modes, as well as including thin lift and trench modes, as well as moisture determinations. The gauge uses an advanced micro-processor-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.
Standards
ASTM D6938 D2950, C1040
AASHTO T310.
The gauge is calibrated by the Five-block calibration method.
• Menu-driven operation—direct readings in engineering units
• AA batteries eliminate charging—6-12 month battery life
• Easy operation handle with positive latch
• Modular design, simplifies repairs
• Automatic depth sensor
Easy to Operate
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.
Easy to Power
The EZ is powered by six standard AA alkaline batteries, which provide up to 2000 hrs of service. No chargers are needed and you can buy batteries almost anywhere.
Easy to Service
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 any repair procedure.
Supplied complete with
