The maximum viscosity ranges correspond to a spiral spindle rotational speed of 1.0 RPM. Lower
spindle speeds are possible but the pumping action within the spiral chamber may not be sufficient to
provide meaningful vicosity data.

In taking viscosity measurements with the DV-II+ Viscometer 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 combination of spindle/speed rotation.
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-II+ Viscometers have a
full scale range precision of (+/-) 1% of any spindle/speed rotation. We discourage taking readings below
