Brinell Rotational Viscometer for Lubricating Oil -70℃ to Room Temp ASTM D2983

SH11145B Brinell rotational viscometer (domestic)

The SH11145B Low Temperature Brinell Viscometer for Lubricating Oil is designed and manufactured strictly in accordance with GB/T11145-2014 Determination of Low Temperature Viscosity of Lubricants using the Brockfeldt Viscometer Method. It is suitable for detecting automotive fluid lubricants with a viscosity range of 1 to 6000000mPa.s, such as gear oil, hydraulic transmission oil, industrial and automotive hydraulic oil.

The method for determining the shear rate viscosity of automotive fluid lubricants involves placing the sample in a cold bath at the test temperature, connecting a Burgundy viscometer and a spindle, selecting the appropriate rotational speed, and maintaining a constant temperature for 2 to 16 hours before measuring the low-temperature Burgundy viscosity of the sample.
