・ In the viscosometer of the appropriate amount, the sample in the time of the ball C (the amount between the mark M1 and the M2) is measured and the time to leak the capillary tube, and seeks the viscosity.
・ It is a standard dynameter that does not require correction of surface tension difference.
・ There are 16 types so that motion viscosity is 0.3 to 100000mm2/s {CST centimbouts}. (With constant indicator)
・ Because the liquid pillar difference is always kept constant, accuracy is higher than SO and SF.
