Digital Residual Pressure Manometer

Digital Residual 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 an 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.

Features:

• The optimal method for fast, accurate vacuum pressure measurements
• Easy to read digital display
• A mercury-free alternative for safe asphalt Rice testing
• NIST Traceable multi-point certification available
