Digital Residual Pressure Manometer

Digital Residual Pressure Manometer

Digital Residual Pressure Manometer

The Digital Residual Pressure Manometer is a precise, mercury-free solution for measuring vacuum levels, commonly used in the asphalt Rice Test. Designed to ensure safety, accuracy, and environmental friendliness, it meets ASTM D2041 and AASHTO T 209 standards for determining the specific gravity and density of asphalt mixtures.

This device features an absolute pressure transducer that provides instant digital readings of applied vacuum from 0 to 1,000mm Hg with a resolution of 0.1mm. The easy-to-read backlit digital display ensures convenience, while its accuracy of ±0.5% of full scale makes it a reliable choice for lab applications. It includes a 0.25in hose barb connection with a needle valve for vacuum tubing. Powered by either a 9V battery or an included AC adapter, this manometer is designed for ease of use.
