More Solutions to Sticky Problems. 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.
