Residual Pressure Manometers

Manometers measure vacuum pressure and are used when performing ASTM D2041 and AASHTO T 209 Asphalt Bulk Specific Gravity (Rice) Tests and for other vacuum applications in the lab.

  • MA-166 Mercury Manometer is a traditional Residual Pressure Manometer with a mercury-filled U-tube mounted to a wooden stand, equipped with a graduated, sliding scale.  
  • MA-170 Digital Absolute Pressure Manometer is a safe, accurate and environmentally-friendly option for measuring vacuum levels. An electronic absolute pressure transducer gives instant readings on the digital display.

**Please check for restrictions on shipment of instruments containing mercury into your area before ordering.
