Direct Cool II
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 -40°C).
Additionally, the multi-purpose Direct Cool II can be used for running the automated low-temperature viscosity test for ATF, hydraulic fluids and gear oils per the new ASTM D2983, Procedure D technique. The dual-position design allows operators to test two samples simultaneously, or the ability to run a reference sample alongside an unknown sample as indicated in the ASTM method.
Methods: ASTM D5133, ASTM D7110, JPI-5S-56-99, Chinese SH/T0732
