- 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
