Low-temperature measurement of viscosities continuously from -5°C to -40°C or below used to characterize the low-temperature rheological performance of lubricating oils and other fluids.  The Scanning Brookfield provides the most complete analysis available on engine oil pumpability in the critical sump-to-pump screen zone and is the only technique capable of generating the Gelation Index and Gelation Index Temperatures. Automated data acquisition and analysis.  Tabular and graphical printout of both parameters.  The viscosity/temperature curve is continuously updated and displayed on the monitor while data is written to disk for later analysis.

The Scanning Brookfield measures the low temperature pumpability and Gelation Index of fresh, sooted, and highly oxidized engine oils by slowly and continuously lowering the test temperature while recording the two values.  Values of Gelation Index above 15 can result in engine failure under certain field conditions of cooling. 

The PlusTwo model also permits running five additional low-temperature tests: MRV-TP1 (ASTM D 4684), Pour Point (D 97), Stable Pour Point (FTM 203C), Kinematic Viscosity (D 445) and Brookfield Viscosity (D 2983).

A patented device for running the Brookfield Viscosity test with a constant temperature liquid bath was developed by Mr. Ted Selby, who also developed the original air bath approach in the 1950's while employed at General Motors Corp.  The SimAir™ Test Cells are exclusively sold with the Tannas SB+2 bath and the King Refrigeration BLB.

Initial development of the Scanning Brookfield Technique and discussion of applications can be found in technical publications.  For more information contact us.
