The King Mini-Rotary Viscometer (MRV) determines borderline pumping temperatures and yield stress determinations of oils and lubricants without the use of chiller baths or thermoelectric cooling. Measures a broad temperature range of + 80°C to – 40°C (176°F to – 40°F) and incorporates patented direct refrigeration technology for better temperature control and precision
