DPV® Digital Paddle Viscometer

For Dynamic Viscosity of Non-Homogenous Materials Including Emulsified Asphalts
ASTM D7226, D2397, D977 and AASHTO TP-121

Common Applications

  • Emulsified asphalts
  • Marine fuels
  • Suspensions
  • Slurries
  • Foods
  • Paints
  • Residual oils

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.

Designed specifically for viscosity testing of non-homogenous materials

  • Meets ASTM (D7226/D2397/D977) and AASHTO provisional standard requirements for asphalt emulsions
  • Viscosity range: 30 mPa·s (cP) to 30,000 mPa·s (cP) in 100-fold increments depending on paddle selection
  • Integrated heating measures dynamic viscosity at 40 °C, 50 °C, 80 °C and 100 °C ± 0.1 °C. For tests at 25 °C, see the TE-DPV product page. 
  • Digital display presents viscosity values in mPa·s (cP), mm²/s (cSt) and Saybolt Fural Second
  • Suitable for applications including emulsified asphalts, marine fuels, suspensions, slurries, foods, paints and residual oils

Improves data quality

  • Automated sample processing and testing reduces dependence on operator skill for quality data
  • Paddle continuously mixes the sample for greater sample homogeniety and more representative sample data
  • Direct measurement of the sample rather than the bath temperature provides more accurate temperature measurement
  • Viscosity data is automatically calculated and may be transferred to an optional dot matrix printer

Eliminates laborious and tedious sample processing

  • No sieving or sample pre-heating is required, just load the sample and push a button to initiate sample prep and testing
  • Removable sample cup allows for quick and easy cleaning between samples
  • Allows unattended sample processing without the need to invest in additional, expensive equipment
  • Computes most tests in 10 to 30 minutes with less messy post-test cleanup

Reduces safety risks

  • No hot dripping sample or tricky cork removal; no glass components or accessories
  • Heater cup thermostat senses over-temperature fault conditions and removes power to the heater until the temperature is at a safe level
  • Motor shaft and paddle immobilization automatically disables motor power

Low cost, easily transportable design

  • Self-contained, compact instrument with no ancillary equipment (e.g. ovens, water baths)
  • Transports easily for field applications. DPV is up to 1/7 the benchtop footprint and 1/3 the weight of a traditional Saybolt viscometer bath
  • Low overall system cost
