ASTM D3829,ASTM D4684 Fully Automatic MRV Tester (Low Temperature Yield Stress & Apparent Viscosity Analyzer)

The Mini-Rotary Viscometer determines borderline pumping temperatures and yield stress of oils and lubricants without the use of chiller baths or thermoelectric cooling.
This Borderline Pumping Temperature Tester is a very good choice for measuring low-temperature pumping viscosity from -5 °C to -40 °C.

Applications:

Drive line lubricants
New engine oils
Used automotive oils
