Determines the resistance of lubricating grease to flow under prescribed conditions. Mobility is measured in grams per second by pumping the sample through a standardized SOD pressure viscometer at controlled temperature and pressure.

Test temperatures as low as –30°F (–34.4°C)

Conforms to the specifications of:

U.S. Steel Method; ASTM Draft Method

Consists of pressure viscometer, cooling bath and refrigeration system.

 The stainless steel pressure viscometer is fitted with a modified No.1, 40:1 ratio capillary.

After the sample is loaded in the pressure viscometer, the assembly is installed in the cooling bath and allowed to reach the test temperature.

Mechanically refrigerated cooling bath can attain test temperatures as low as –30°F (–34.4°C) with stability of ±2°F (±1°C).

With the sample at the test temperature, the flow of grease is started under the selected pressure on a nitrogen tank regulator.

Flow per second is determined by collecting the grease for a specified period.

Includes sample collector turntable.
