Digital Residual Pressure Manometer

Digital Residual Pressure Manometer is a mercury-free, eco-friendly alternative for vacuum pressure measuring during lab applications. The manometer meets test standards AASHTO T 209 and ASTM D2041 to measure Theoretical Maximum Specific Gravity and Density of Asphalt Mixtures (Rice Test).

Accurate to ±0.5% of full scale, the precision gauge utilizes an absolute pressure transducer to provide instantaneous readings of applied vacuum from 0 to 1,000mm Hg on a digital display with 0.1mm resolution. The Manometer is powered by either a 9V battery or AC adapter, both included. This unit also includes a 0.25in (6.35mm) hose barb connection with a needle valve for vacuum tubing.

Models with NIST calibration certification meet AASHTO T 209 method.
