Cannon-Manning Vacuum Viscometers

Calibrated CMVC Series

For measurement of viscosity of highly viscous materials such as asphalt cement at 60 °C (140 °F) according to ASTM D 2171. Applicable to materials with viscosity range of 0.036 to 80,000 poise. Vacuum of 300 mm Hg is applied to small arm with timing bulbs; two bulbs are incorporated to extend viscosity range of viscometer.

Provided with ISO/IEC 17025 certificate of calibration and instruction sheet.

Calibrated CMVC-RO Series (not shown)

Same as 9724-H50 series, but with permanently attached round metal holder, for hole 51 mm (2 inches) in diameter.
