Residual Pressure Manometers

Manometers measure vacuum pressure and are used in determining specific gravity and density of asphalt mixtures (often called the Rice Test). They meet ASTM D2041 and AASHTO T 209 requirements and are available in digital and glass-tube models. Glass tube manometers use mercury as an indicating fluid. Mercury is purchased separately through other suppliers.

Please check local regulatory restrictions carefully before ordering or using Mercury.


Digital Absolute Pressure Manometer
Models: MA-170, MA-170F, MA-170C, MA-170FC
  • Digital Absolute Pressure Manometers are environmentally-friendly, safe to use and offer accurate measurements of vacuum levels. They provide instant digital readings on an easy-to-read backlit display and are available with or without NIST Certification.
  • Glass-Tube Manometer is mounted on a wooden stand with flat base. Mercury is required as an indicating fluid and can be purchased separately from an outside supplier.
