Sheen-Opac Opacity Reflectometer
An easy to use hand-held instrument for measurement of the opacity, or luminuous 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.
- Automatic calibration on 2 included calibration standards
- Large backlit LCD display of individual readings
- Rechargeable batteries, with dual voltage mains battery recharger supplied.
The instrument 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. A completely black surface will read a (zero), whilst a perfect white will be 100 units, recognised in colour measurement scale as the 'Y' value.
Sheen-Opac can be used for comparison of contrast ratios (hiding power) of paints. The procedure involves applying the test sample onto black and white card (our Ref SH301) or onto polyester sheets (our Ref SH1136) which is then placed over black and white glass plates.
Readings are taken on the coating over the black portion followed by a reading taken over the white portion.
