Introduction
I. INTRODUCTION
The CAP Series Viscometers are Cone and Plate geometry high shear rate
instruments with integrated temperature control of the test sample material. The
CAP1000+isaxedshearrateviscometerrotatingat750RPMand900RPM.
The instruments operate by digital setting and display; rotational speed can be
automatically timed to stop. High shear rate viscosity measurements are made
over various viscosity ranges depending upon the cone spindle and the rotational
speed (shear rate). Viscosity is selectively displayed in units of centipoise (cP), poise
(P),milliPascalseconds(mPa•s)orPascalseconds(Pa•s).Temperaturecontrolof
sample is possible between either 5°C (or 15°C below ambient, whichever is higher)
and 75°C or 50°C and 235°C depending on viscometer model.
The CAP1000+ can also be ordered with a single, customized speed between 5 and
1000 rpm. In this case, the CAP can offer, when necessary, low shear rate capability.
