Rhopoint Instruments IQ 20/60 Gloss, Haze & DOI Meter

The Rhopoint IQ is an incredibly advanced instrument that measures reflected image quality; it is the only handheld instrument that profiles how light is reflected from a surface.

What does it measure?:

• Gloss levels at 20° and 60°
• Haze
• Distinctness Of Image (DOI)
• Reflected Image Quality (RIQ)
• Peak Gloss Level (RSPEC)

Terminology:

• Gloss: A measurement proportional to the amount of light reflected from a surface measured at 20° (high-gloss) and 60° (mid-gloss).
• Haze: An optical effect caused by microscopic textures or residue on a surface.
  • Symptoms: A milky finish is apparent on the surface with a loss of reflected contrast. Halos and patterns can be seen around reflections.
  • Causes: Poor dispersion, raw material incompatibility, additive migration, vehicle quality, drying/curing conditions, polishing marks, fine scratches, ageing, oxidisation, poor cleanliness/surface residue.
• DOI: A measure of how clearly a reflected image will appear in a reflective surface
• RIQ: Used to quantify effects such as orange peel and surface waviness. This new parameter gives higher resolution results compared to Distinctness of Image (DOI) measurement and better mimics human perception of surface texture, especially on high-quality finishes found on automotive paint.
  • Symptoms: Orange peel, brush marks, waviness or other structures visible on the surface. Reflected images are distorted.
  • Causes: Application problems, incorrect coating flow, coating viscosity too high or low, sag or flow of coating before curing, incorrect particle size/distribution, overspray, improper flash/recoat time, incorrect cure times and cure temperature.
• RSPEC: The peak gloss value over a very narrow angle.
