An easy to use hand-held reflectometer for measurement of the opacity, or luminous reflectance, of a grey scale. Suitable for the evaluation of a coatings’ hiding power, or simple shade sorting tasks of metallised films, anodized aluminium or ceramics.

The Opac Opacity Reflectometer (310) measures the diffusely reflected light from the test surface. The controlled conditions of illumination and angle of illumination allow surfaces to be characterised according to their lightness or darkness.
