Description

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.

Specification

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
  • BS 3900-D4
  • ASTM E1347 Standard Test Method for Color and Color-Difference Measurement by Tristimulus Colorimetry
  • ASTM D4214 Standard Test Methods for Evaluating the Degree of Chalking of Exterior Paint Films
  • ASTM D2805 Standard Test Method for Hiding Power of Paints by Reflectometry
  • ASTM D589-97 Standard Test Method for Opacity of Paper (15°Diffuse Illuminant A, 89% Reflectance Backing and Paper Backing)
