ABSTRACT:
This invention relates to an arrangement for determining the degree of dispersion of magnetic pigments in a dispersion, in which the magnetic dispersion flowing along a transparent tube or a transparent wall is irradiated with an illuminating and image forming device and the light diffusely reflected from the dispersion is measured in a detector as to its color and/or brightness and indicated in an evaluating device.
