Features & Benefits
Automated and precise determination of direct kinematic viscosity at 40 °C and 100 °C*
- Provides kinematic viscosity measurement without the need to correlate dynamic viscosity data
- Cools from 100 °C to 40 °C in ~30 minutes
- Viscosity range
- Standard range tube provides viscosities from 10 to 700 mm²/s (cSt) at 40 °C and 5.5 to 200 mm²/s (cSt) at 100 °C
- Low range tube provides viscosities from 2 to 140 mm²/s (cSt) at 40 °C and 100 °C
- Follows ASTM D7279 and offers near ASTM D445 precision due to exceptional temperature control (±0.05 °C)
- Rapid cycle time of 3 to 5 minutes from sample injection to test result
Portable, self-contained and dependable
- Weighs approximately 10 lb and takes up less space than a coffee maker
- Does not require a PC or any external utilities
- Optional power inverter enables the instrument to run off of a 12 Vdc vehicle charging port
- Rugged, reliable design has only two moving parts
Simple & safe operation
- Graphical touch screen provides step-by-step test instructions
- Factory calibrated; no gauges or valves to adjust
- Solid-state temperature control eliminates need for liquid bath
- Intrinsically safe unit operates on 12 Vdc power
- Optional printer available
Economical
- Low cost of ownership
- Requires only 10 to 15 mL of solvent and 0.5 mL of sample per test
- No sample vials required; sample is injected directly into the instrument
*The unit can store two temperatures and is pre-calibrated at 40 °C and 100 °C but custom calibration at any two temperatures between 40 °C and 100 °C is available on request.
