DOI / RIQ Meter, (quantify orange peel) Hazemeter (reflectance haze) 20/60˚ Glossmeter for high gloss finishes This incredibly advanced instrument measures: GLOSS • HAZE• REFLECTED IMAGE QUALITY (RIQ) • DISTINCTNESS OF IMAGE (DOI) • RSPEC.

• 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.
• 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 such as automotive paint finish.
• DOI: A measure of how clearly a reflected image will appear in a reflective surface.
• RSPEC: The peak gloss value over a very narrow angle
