Asphalt Specific Gravity Testing Equipment

MA-170C undergoes multi-point calibration at 25, 30 and 35mm Hg on NIST traceable equipment, and is supplied with a NIST Calibration Certificate to meet AASHTO T209 requirements. 

The Digital Absolute Pressure Manometer is widely used for the asphalt Rice Test and is a safe, accurate and environmentally-friendly alternative for measuring vacuum levels for all lab applications. These models meet the requirements of ASTM D2041 and AASHTO T 209 to measure specific gravity and density of asphalt mixtures, often called the Rice Test.

The gauge is mercury-free and uses an absolute pressure transducer to give instant digital display of applied vacuum from 0 to 1,000mm Hg with 0.1mm resolution. Digital readings are provided on an easy-to-read backlit display. Accuracy is ±0.5% of full scaleA 0.25in hose barb connection with a needle valve is supplied for vacuum tubing. Powered by a 9V battery or AC adapter, both included. Automatic shut-off saves power in battery mode.

NIST calibration or recalibration is available by ordering MAA-25 Calibration.
