RHOPOINT-Novo-Shade Duo

SKU: RHOPOINT-Novo-Shade Duo  /   Manufacturer:

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).


  • 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
