Asphalt Institute Vacuum Viscometers

Asphalt Institute Vacuum Calibrated AIVC (9724-R50) Series Similar to Cannon-Manning Vacuum (CMV, 9724-H50) series, but with graduated capillary instead of two timing bulbs. Read more about the significance of expanded uncertainty. Provided with certificate of calibration and instruction sheet. Asphalt Institute Vacuum Calibrated AIVC-RO (9724-T50) Series Same as 9724-R50 series, but with permanently attached round metal holder, for hole 51 mm (2 inches) in diameter. Minimum sample size 3 mL. Require bath depth of 180 mm (7.1 inches). Holder is not supplied. For holder, see 9726-N15 Note: For sizes 400R and 800R, the “roofing” design is normally used for segment B, which extends the viscosity range to 1,400,000 and 5,800,000 poise, respectively. See ASTM D 2171, Table X2. Viscometers with special constants are available by special order at additional cost.
