TE-DPV® Asphalt Thermoelectric Rotational Paddle Viscometer

ASTM D7226, ASTM D2397, ASTM D977 and AASHTO TP 121 (T 382)
For Dynamic Viscosity of Non-Homogeneous Materials Including Emulsified Asphalts

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

TE-DPV® Asphalt is an automated, thermoelectrically cooled rotational digital paddle viscometer for measuring the dynamic viscosity of emulsified asphalts, marine fuels and other non-homogeneous materials at 25 °C, 40 °C, 50 °C, 80 °C, and 100 °C. The TE-DPV® Asphalt provides a convenient, 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 TP121 for asphalt emulsions
  • Viscosity range: 30 mPa·s (cP) to 3000 mPa·s (cP)* ± 5% accuracy.
  • Integrated heating and cooling enables dynamic viscosity measurement at 25 °C, 40 °C, 50 °C, 80 °C and 100 °C ± 0.1 °C
  • Digital display presents viscosity values in mPa·s (cP) as well as mm²/s (cSt) for samples with known density values

Improves data quality

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

Eliminates laborious and tedious methodologies

  • Simply load the sample and push a button to initiate testing
  • Removable sample cup make cleaning between samples quicker and easier
  • Enables unattended sample processing
  • Completes most tests in 10 to 30 minutes

Reduces safety risks

  • No hot dripping sample; no glass components or accessories
  • Wipe-clean paddle and sample cup reduce the need to use hazardous cleaning solvents
  • Heater cup thermostat senses over-temperature fault conditions and removes power until temperature reaches a safe level
  • Motor shaft and paddle immobilization automatically cuts off motor power

Low cost, easily transportable design

  • Self-contained, compact instrument with no ancillary equipment
  • At 1/7 the benchtop footprint and 1/3 the weight of traditional Saybolt viscometer baths, the TE-DPV conserves valuable lab space and transports easily for field applications
