DPV® Asphalt is an automated, rotational digital paddle viscometer for measuring the dynamic viscosity of non-homogeneous materials such as emulsified asphalts, marine fuels, residual oils and slurries at 40 °C, 50 °C, 80 °C and 100 °C. The DPV Asphalt provides a automated alternative to older, labor-intensive and less precise methods.
Designed specifically for viscosity testing of non-homogeneous materials
- Meets ASTM D7226,D2397,D977 and AASHTO provisional standard requirements for asphalt emulsions
- Viscosity range: 30 mPa⋅s (cP) to 3,000 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. Factory calibrated at 50 °C.
- Digital display presents viscosity values in mPa⋅s (cP),mm2/s (cSt)
- 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 for quality data
- Paddle continuously mixes the sample for greater sample homogeneity and more representative sample data
- Direct temperature measurement of the sample,rather than the bath,provides more accurate measurements and results
- 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 – save time and labor
- Completes most tasks in 10 – 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
- Easier to clean,reduces hazardous/chemical waste
Low cost,easily transportable design
- Self-contained,compact instrument with no ancillary equipment (e.g. ovens,water baths)
- Transports easily for field applications. DPV Asphalt is up to 1/7 the benchtop footprint and 1/3 the weight of the traditional Saybolt system
- Low overall system cost
