Industry standard Concrete Clarity Meter
The Concrete Clarity Meter (CCM) quantifies surface quality problems that are invisible to a standard glossmeter and profiles how light is reflected from a surface. This incredibly advanced instrument measures:
20/60° GLOSS • HAZE• REFLECTED IMAGE QUALITY (RIQ) • DISTINCTNESS OF IMAGE (DOI) • RSPEC
In practice, these terms mean:
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.
The concrete clarity meter 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.
Orange peel dramatically reduces appearance quality without affecting gloss readings. These two test panels measure have identical gloss values but are visually very different.. The Rhopoint Conrete Clarity Meter can quantify the differences.
Achieve consistent finishes
Using the Rhopoint Concrete Clarity Meter can help to achieve more consistent surface finishes. Images reflected in the surface appear sharp and clear.
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: It is very sensitive to surface texture and can be used to identify subtle differences in smooth surfaces.
Reflective 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. Causes: Poor dispersion, raw material incompatibility, additive migration, vehicle quality, stoving/drying/curing conditions, polishing marks, fine scratches, ageing, oxidisation, poor cleanliness/surface residue.
Reflective Haze Compensation
The instrument compensates for reflection from within the coating for highly reflective pigments, metallic coatings and speciality pigments, allowing the haze of any painted surface to be measured
Reflected Image Quality (RIQ)
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. Symptoms of Poor RIQ: 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/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.
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 Concrete Clarity Meter.
Distictness Of Image (DOI)
A measure of how clearly a reflected image will appear in a reflective surface.
