Novo-Shade Duo

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
