The Novo-Shade Duo reflectometer can be used to assess either the shade of a surface (a simple indication of colour based on lightness/darkness) or calculate the opacity of a coating, plastic film or paper sample.
Main functions:
- Measures using the 0/45º geometry
- 2 modes of operation: shade (grayscale) or opacity (hiding power)
- Automatic calibration mode for safe and fast calibration
- Continuous-read feature for quickly checking large surfaces
- Statistical analysis gives an instant indication of batch quality
- Download, analyse and store readings in Novo-Soft
- Extended two year warranty - free for registered products
- Extended life light source - over 10 years operation
Technical Parameters:
- Resolution: 0.1GU
- Repeatability: 0.2%
- Reproducibility: 0.5%
- Measurement area: 15 x 10mm ellipse
- Shade mode (0% = black,no reflectance; 100% = brilliant white – full reflectance)
- Opacity mode (0% = completely transparent; 100% = fully opaque)
Standards:
- ISO 2814 Paints and varnishes - Comparison of contrast ratio (hiding power) of paints of the same type and colour
- ISO 6504 Paints and varnishes - Determination of hiding power - Part 3: Determination of contrast ratio (opacity) of light-coloured paints at a fixed spreading rate
