Cleanliness meter

The instrument is suitable for quality control measurement in the laboratory or on site. Any surface, lightness or darkness can be measured. The instrument gives objective measurements for the hiding power of coatings and inks and performs basic shade sorting for materials such as paper, plastics, ceramics and anodised aluminium. Using the same optical geometryas of most colorimeters, it is an illuminant in close conformance to CIE 'C'.
