Novo-Shade Duo+ Reflectometer

The Novo-Shade Duo reflectometer has 3 modes of operation

This is used for measuring the hiding power of a coating or plastic film
Measure the shade of surface on a greyscale
Measure the substrate cleanliness or oxidisation of a surface


  • Measures using the 0/45º geometry
  • 2 modes of operation: shade (grayscale) or opacity (hiding powe 
  • Measures using the 0/45º geometry
  • Fast measurement, single button push initiates measures of defined parameters
  • Shade measurement displayed instantly on screen
  • Automatic calculation of opacity and cleanliness
  • On-board statistical analysis with graphical trend analysis (graphs available in shade mode only)
  • Direct data input via Bluetooth – instantly transmit measured readings directly to programs such as Microsoft Excel
  • Date and time stamped results
  • Automatic calibration with tile validation
  • Compatible with all major international standards
