ASTM D7110
ASTM D2983
JPI-5S-56-99
Chinese SH/T0732


About

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.
