The new CANNON® High-Temperature High-Shear (HTHS) Capillary
Viscometer is designed to determine the viscosity of engine oils and other oils
under conditions of high shear at high temperatures. The HTHS is capable of
testing at 1.4x106 s-1 at 150°C, and meets all precision
specifications of ASTM D 5481.
Oil samples are introduced into the viscometric cells and then flow through
small glass capillaries under pressure to achieve the desired shear rate. The
HTHS monitors each test and displays the results. You can also analyze, display,
and print test data with the computer software.
The HTHS viscometer is supplied with a digital temperature control system
(variable from 30°C to 150°C), a digital pressure measuring system, automatic
timer, and the High Shear Viscosity Calculator (Standalone software package for
Windows® for HTHS data analysis and output).
