The Ravenfield® HTHS BS/C+ Viscometer is a compact, high precision, tapered plug viscometer that measures the high
temperature, high shear viscosity of engine lubricants and other oils according to ASTM D4741, CEC L-36-A-90 and IP 370 as specified by SAE J300 and ACEA. The BS/C+ HTHS Tapered Plug Viscometer also correlates to ASTM D4683 with no bias
and is capable of testing across a wide range of temperatures and shear rates.
