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 scale. A 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.
The Digital Absolute Pressure Manometer is mercury-free and gives on-the-spot digital display of applied vacuum pressure from 0—1,000mm Hg.
Overall Dimensions: 3.1x6.5x1.18in (78.7x165.1x30mm), WxDxH.
