The SBT® test measures the 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.
