SBT™ Direct Cool

Scanning Brookfield Technique – Low-Temperature Pumpability & Gelation Index

The Scanning Brookfield Technique™ (SBT™) measures apparent viscosity of fresh, sooted, or highly oxidized engine oils at low temperatures. It determines the susceptibility of engine oils to flow-limited and air-binding responses during slow cooling conditions by providing continuous rheological data over a broad temperature range (+90°C to -45°C).

Methods:
ASTM D5133
ASTM D7110
JPI-5S-56-99
Chinese SH/T0732

  • The non-liquid system eliminates flammable bath mediums from laboratory environments.
  • Dual position, independent test sample design.
  • Simple vertical alignment and centering of viscometers.
  • Small bench-top footprint.
  • Self-contained pre-heating: Heats samples to 90°C prior to analysis, while remaining in position.
  • Internal automatic dry air system removes moisture that accumulates during the test.
  • Programmable Temperature Controller maintains bath temperature within ±0.1°C to -45°C.
  • The enhanced SBT™ Automation Package (with laptop) offers the capacity to operate up to four, 2-place, Direct Cool units simultaneously and independently.
