<a> Computed for standard Torsion Spring (F 1.0). For other torsion springs, multiply by F factor. <b> Lower viscosities can be measured by the Model 800, however one must take into account the effect of bearing drag, Taylor vortices, zero offset, etc. when looking at the expected accuracy of the reading.
