The CANNON® High-Temperature High-Shear Capillary Viscometer (HTHS Series II) 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 1.4 x 106s-1 at 150°C and meets all precision specifications of ASTM D 5481 and SAE J300. The Series II design incorporates simple one-button operation - just load samples, set pressure, and press the Start button. If desired, variable shear rates (? 30 percent of the shear rate specified in ASTM D 5481) may be obtained by altering the test pressure (variable from 75 to 500 psi). The viscosity range of 2-7 mPa.s can be extended to more than 20 mPa.s with custom configuration.
