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.

Model: MA-167
  • 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.
