DPV® Asphalt Digital Paddle Viscometer
Available from Cannon Instrument Company
For Dynamic Viscosity of Non-Homogenous Materials Including Emulsified Asphalts
ASTM D7226, D2397, D977 and AASHTO TP-121
The DPV is an automated, rotational digital paddle viscometer for measuring the dynamic viscosity of non-homogenous materials such as emulsified asphalts, marine fuels, residual oils, slurries and foods at 40 °C, 50 °C, 80 °C, and 100 °C. For tests at 25 °C, see the TE-DPV product page. The DPV provides an automated alternative to older, labor-intensive and less precise methods.
