The
Asphalt Institute Vacuum Viscometer measures the viscosity of highly viscous
materials according to ASTM D2171. Minimum sample volume is 3 mL. Minimum bath
depth is 180 mm (7.1 in). Viscometers are provided with a certificate of
calibration and instruction sheet. Permanently attached round metal holders are
included or may be ordered separately.
