THE RHOPOINT IQ IS THE ULTIMATE GLOSSMETER UPGRADE IQ GLOSS measurements are fully compatible with existing Novo-Gloss and Micro-Tri-gloss results. Dualgloss 20/60 or Trigloss 20/60/85 versions are for maximum accuracy and resolution in all gloss applications.

THE RHOPOINT IQ QUANTIFIES SURFACE QUALITY PROBLEMS THAT ARE INVISIBLE TO A STANDARD GLOSSMETER The Rhopoint IQ measures reflected image quality; it is the only hand held instrument that profiles how light is reflected from a surface. Glossmeters are usually used to measure the “shininess” of a surface but are not sensitive to common effects which reduce appearance quality. THE RHOPOINT IQ MEASURES 20/60/85 GLOSS RSPEC REFLECTANCE HAZE REFLECTED IMAGE QUALITY DISTINCTNESS OF IMAGE GONIOPHOTOMETRIC CURVES GLOSS – A measurement proportional to the amount of light reflected from a surface. Geometry: The correct measurement geometry should be used according to the sample finish – Matt: 85 , Mid Gloss: 60 , High Gloss: 20 . RSPEC – The peak gloss measured over a very narrow angle. Usage – is very sensitive to surface texture and can be used to identify subtle differences in smooth surfaces. REFLECTANCE HAZE – An optical effect caused by microscopic texture or residue on a surface. Visible Symptoms: A milky finish is apparent on the surface with a loss of reflected contrast. Halos and patterns can be seen around reflections of high intensity light sources. Orange peel dramatically reduces appearance quality without affecting gloss readings. These two test panels measure identically with a standard glossmeter, the Rhopoint IQ with RIQ/DOI measurement can quantify the differences. Causes: Poor dispersion, raw material incompatibility, additive migration, vehicle quality, stoving/drying/curing conditions, polishing marks, fine scratches, ageing, oxidisation, poor cleanliness/surface residue. – RIQ is 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. REFLECTED IMAGE QUALITY (RIQ) Symptoms of Poor RIQ: Orange peel, brush marks, waviness or other structures visible on the surface. Reflected images are distorted. Haze is a common problem associated with coatings and polished materials. Surfaces with haze have a “milky” finish with a “shallow” reflected image. This important characteristic is directly measured with the Rhopoint IQ. Causes: Application problems, incorrect coating flow, coating viscosity too high/low, sag or flow of coating before curing, incorrect particle size/distribution, overspray, improper flash/recoat time, inter coat compatibility, incorrect cure times and cure temperature. – A measure of how clearly a reflected image will appear in a reflective surface.
