ASPHALT INSTITUTE VACUUM VISCOMETERS

Asphalt Institute Vacuum Calibrated AIVC Series

Similar to 9724-H50 series, but with graduated capillary instead of two timing bulbs. Provided with certificate of calibration and instruction sheet.

  • Minimum sample size 3 mL. Require bath depth of 180 mm (7.1 inches).
  • Note: For sizes 400R and 800R, the “roofing” design is normally used for segment B, below, which extends the viscosity range to 1 400 000 and 5 800 000 poise, respectively.

Asphalt Institute Vacuum Calibrated AIVC-RO Series

 Same as 9724-R50 series, but with permanently attached round metal holder, for hole 51 mm (2 inches) in diameter.
