Novo-Shade Duo Reflectometer

Novo-Shade Duo Reflectometer

Product 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.

Measuring using 0/45º the Novo-Shade Duo measures the colour of a surface and not the specular reflectance (gloss).

Features:

  • 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 Specification:

  • Resolution: 0.1GU
  • Repeatability: 0.2%
  • Reproducibility: 0.5%
  • Battery life: 15,000+ readings
  • Dimensions: 125 x 50 x 100mm
  • Weight: 470g
  • 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)

Applications

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. Measuring using 0/45º the Novo-Shade Duo measures the colour of a surface and not the specular reflectance (gloss). In Shade Mode the Novo-Shade Duo can help maintain the production quality of the following:

  • Shade of paints, inks and coatings
  • Fading of textiles and plastics
  • Chalking of paint
  • Efficiency of detergents and bleaching agents
  • Whiteness of recycled paper
  • Cleanliness and oxidisation on metal surfaces

In Opacity Mode the Novo-Shade Duo can help maintain the production quality of the following:

  • Hiding power of paints, inks and coatings
  • Transparency of plastic film
  • Opacity of paper
