TE-DPV® Asphalt Thermoelectric Rotational Paddle Viscometer
In stock
TE-DPV Asphalt is an automated, thermoelectrically cooled rotational digital dual-paddle viscometer for measuring the dynamic viscosity of emulsified asphalts at 25 °C, 40 °C, 50 °C, 60 °C, and 70 °C. The TE-DPV Asphalt provides a convenient, automated alternative to older, labor-intensive, and less precise methods.
Conforms to test methods ASTM D7226, ASTM D2397, ASTM D977, and AASHTO T 382.
Common applications are emulsifited asphalts, maine fuels, suspensions, slurries, and residual oils.
Designed specifically for viscosity testing of emulsified asphalt
- Meets ASTM D7226, D2397, D977, and AASHTO TP 382 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,60 °C and 70 °C (± 0.1 °C); CANNON calibrated at 50 °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 on data quality
- Dual paddles continuously mix the sample for greater homogeneity and more representative data
- Direct temperature measurement of sample, rather than the bath, improves measurement accuracy and results
- 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 makes cleaning between samples quicker and easier
- Unattended sample processing saves time and labor
- Completes most tests in 10 to 30 minutes
Reduces safety risks
- No hot dripping sample; no glass components or accessories
- Wipe-clean paddles 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 cut 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 Asphalt conserves valuable lab space and transports easily for field applications
