accurate and repeatable torque reading under any measurement circumstance. However, the
conversion of this torque reading to centipoise will only be correct if the factor used was developed
for those specific conditions. Brookfield has outlined a method for recalibrating a Brookfield
Viscometer/Rheometer to any measurement circumstance in More Solutions to Sticky Problems,
Section 3.3.10. It is important to note that for many viscometer users the true viscosity is not as
important as a repeatable day to day value. This repeatable value can be obtained without any special
effort for any measurement circumstance. But, it should be known that this type of torque reading will
not convert into a correct centipoise value when using a Brookfield factor if the boundary conditions
are not those specified by Brookfield.
The guard leg is a part of the calibration check of the Brookfield LV and RV series Viscometer/
Rheometer. Our customers should be aware of its existence, its purpose and the effect that it may have
on data. With this knowledge, the viscometer user may make modifications to the recommended
method of operation to suit their needs.
