PFUND BLACK & WHITE CRYPTOMETER
A simple and rapid test method to determine opacity in terms of hiding and spreading powers. This precision instrument is suitable for production and quality control purposes, particularly when product specifications are based on the evaluation of wet films instead of dry coatings. The measurement is made simply by searching the position on the engraved scale where the wet coating, trapped between the wedged top plate and the scale, perfectly hides the background.
