Modified Koppers Vacuum Calibrated MKVC (9724-W50) Series
For measurement of viscosity of asphalts at 60°C (140°F) in accordance with ASTM Standard D 2171. Applicable to materials with viscosity range of 42 to 200 000 poise. Two-piece design, with sample reservoir and calibrated capillary. Vacuum of 300 mm Hg must be applied to top of capillary tube. Read more about the significance of expanded uncertainty.
Provided with certificate of calibration and instruction sheet.
- Minimum sample volume 2 mL. Require liquid bath depth of 178 mm (7 inches).
- Holder is not supplied. For holder, see 9726-N30
Viscometers with special constants are available by special order at additional cost.
