miniPV Addendum
Foreword:
Thank you for purchasing the miniPV viscometer-part of the popular
CANNON minAV family. This ADDENDUM to the current miniAV
Instruction & Operational Manual is intended to provide the operator
with information on the few operational differences between the miniAV
and the miniPV. Please note the following sections of the miniAV
manual where users of the miniPV will need to refer to this
addendum.
Section 1 Introduction
Section 1 Measuring Viscosity
Section 1 Specifications
Section 2 Testing Samples
Section 4 VISCPRO Polymer Equations
Section 4 View Analysis
Section 6 Analysis Configuration Options
Section 7 Sample Data Table
SECTION 1:
miniPV Function:
The miniPV is a fully automated kinematic viscometer specially
designed to handle the unique needs of polymer analysis laboratories
for viscosity determination of polymer solutions. The miniPV instrument
may be used for determination of the relative, inherent, and reduced
viscosity of polymers. Viscosity and Intrinsic values can also be
reported and the intrinsic viscosity can be determined by two single-
point methods or the more rigorous Huggins-Kraemer analysis. At the
core of the instrument resides the miniAV foundation-providing a
familiar system and software user interface. The miniPV differs from the
miniAV in the following ways:
Special coating
