Rotational Viscosity Coefficient (γ1) Measurement System  Model LCM-2

This model can measure data necessary for the calculation of the rotational viscosity (g1) of liquid crystal cells (electric current and time at director switching peak or impurity ion peak) without magnetic field application unit. In addition, voltage holding ratio, ion density, and residual DC voltage also can be measured.
