Viscosity (cP)
In taking viscosity measurements with the DV-III+ Rheometer there are two considerations which
pertain to the low viscosity limit of effective measurement.
1) Viscosity measurements should be accepted within the equivalent % Torque Range from
10% to 100% for any spindle/speed combination.
2) Viscosity measurements should be taken under laminar flow conditions, not under turbulent
flow conditions.
The first consideration has to do with the precision of the instrument. All DV-III+ Rheometers have a
