SB+2 w/computer |
The Scanning Brookfield Technique family of instruments (SB+2, SB+4, SB+8) are used to characterize the low-temperature rheological performance of lubricating oils and other fluids. The SBT 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. 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. Low-temperature measurement of viscosities from -5°C to -40°C or below. Automated data acquisition and analysis. Tabular and graphical printout of Gelation Index and Gelation Index Temperature. The viscosity/temperature curve is continuously updated and displayed on the monitor while data is written to disk for later analysis. The SB+2 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). The SB+2 can achieve and maintain bath temperatures down
to -70°C. Initial development of the technique and discussion of applications can be found in technical publications. For more information contact us. |
