The theory of the Stokes viscometer The theory of the Stokes viscometer is based on the study of the free fall of the ball in investigated liquid.

TOKI SANGYO sells standard fluids for viscometer calibration conform-ing to the JIS Z 8809 viscometer calibration fluid standard. Viscosity values of the fluids are certified (with values) by the National Institute of Advanced Industrial Science and Technology and the fluids are sup-plied with test certificates. Temperature-viscosity computation tables, in 0.1В°C increments, are also attached cometers are used for measuring the viscosity of Newtonian fluids, i.e., a fluid having a viscosity that is independent of the shearing stress or rate of shear, or the apparent viscosity
