Spindle Range Data
This Universal Spindle Range table lists the Spindle Range Coefficients for all (6) T-bar spindles. Dividing the coefficient number
by any rotational speed will give the full scale viscosity range for a Viscometer/Rheometer spindle/speed combination. (The Auto
Range key on DV-E, DV-I+, DV-II+ or DV=III+ instruments provides this information in the digital display).
