  • Measure small and curved surfaces using 20° angle (high gloss)
  • Gloss /DOI / RIQ Meter, (quantify orange peel)
  • Hazemeter (reflectance haze)
  • Custom adaptors available for the measurement of non-flat surfaces

Previously only available for measuring flat surfaces, this technology is now available in a new format specifically designed for curved surfaces, as well as small and delicate parts. Flex 20 gloss measurements are fully compatible with existing Rhopoint IQ results.

The Rhopoint IQ Flex 20 can measure:

  • 20° Gloss
  • Reflectance haze
  • Reflected Image Quality (RIQ)
  • Distinctness of Image (DOI)
  • Goniophotometric curves
  • RSPEC (peak specular reflectance)

The Rhopoint IQ Flex 20 quantifies surface quality problems such as orange peel and haze that are invisible to a standard glossmeter. It profiles how light is reflected from a surface.

Combined gloss, haze and orange peel (DOI/RIQ values) information has made the IQ essential for controlling appearance finish. The Rhopoint IQ Flex 20 brings this technology to a new format specifically designed for curved surfaces, as well as small and delicate parts.

The IQ Flex 20 uses a 512 element linear diode array which profiles reflected light in a large arc from 14° to 27°. The instrument processes this high resolution data, selecting individual elements within the array that equate to the angular tolerences outlined in international measurement standards.


  • Simultaneous measurement of all parameters, date and time stamped.
  • Displays full statistics for the number of readings in the current batch.
  • Graphical reporting for quick trend analysis.
  • Pass / Fail parameters can be defined for instant identification of nonconformances.
  • Different types of surface textures produce identifiably shaped reflectance profile. This goniophotometric data can be downloaded to a PC for further analysis and comparison via the USB cable or Bluetooth data widget.
  • View and inspect data saved on the instrument.
  • Custom adaptors will increase the repeatability of measurement for irregular shaped objects, curved surfaces or small parts.
  • UKAS certification included
