Profile: King Refrigeration, Inc. specializes in low-temperature laboratory instruments for testing engine oils, lubricants and related fluids. Our instruments include cloud and pour point, low temperature kinematic viscosity bath, high temperature kinematic viscosity bath & MRV/TP1 mini rotary viscometer. Our mini rotary viscometer is capable of measuring over a broad temperature range of + 80°C to - 40°C (176°F to - 40°F). It consists of direct refrigeration technology which eliminates the need for liquid cooling mediums such as methanol and the internal gas system provides a continuous blanket of dry gas over samples to eliminate moisture buildup. The test cells are removable that allows for easy cleaning, sample agitation and sample preparation.
