Rhopoint Concrete Clarity Meter (CCM)
The Rhopoint IQ 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.
Distinctness of Image (DOI)
A measure of how clearly a reflected image will appear in a reflective surface and is used to quantify effects such as orange peel and surface waviness.
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 Concrete Clarity Meter
Surface with high haze
Orange peel dramatically reduces appearance quality without affecting gloss readings. The Rhopoint IQ Concrete Clarity Meter with DOI measurement can quantify the differences
Surface with poor DOI
– 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: Resin transfer, lack of refinement, burnish and polishing marks, fine scratches, poor cleanliness/surface residue.
|LEVEL||NAME||DISTINCTNESS 0F IMAGE (DOI) GLOSS||IMAGE CLARITY VALUE, %||LEVEL|
|1||Flat||Images of objects being reflected have a flat appearance.||0-9||<10|
|2||Satin||Images of objects being reflected have a matte appearance.||Okt-39|
|3||Polished||Images of objects being reflected do not have a sharp and crisp appearance but can be easily identified.||40-69|
|4||Highly||Images of objects being reflected have a sharp and crisp appearance as would be seen in a near-mirror like reflection. May require grouting||70-100|
DISTINCTNESS OF IMAGE (DOI) GLOSS
DOI is the sharpness of images of objects produced by reflection at a polished surface, sometimes called image clarity
Measurement by Image Clarity Meter (ASTM D5767): The DOI, Image Clarity Value, obtained from this test method, range from 0 to 100 with a value of 100 representing perfect DOI (image clarity).
Haze is the cloudiness or milky appearance of images of objects produced by reflection in a polished surface
The minimum number of tests distributed across the polished surface should be three for areas up to 1000 ft² and one additional test for each 1000 ft² or fraction thereof. This applies to both the Image Clarity Value and Haze Index.
Specifications Rhopoint Concrete Clarity Meter (CCM)
|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 – mid gloss: 60°, high gloss: 20°.|
|20°||Improved accuracy and resolution on high gloss & metallic samples (>70GU when measured at 60°) Measurement range: 0-2000 GU|
|60°||Universal angle – all gloss levels|
|Measurement range: 0-1000 GU|
|Measurement range||0-100 GU||100-2000GU|
|DOI||Resolution 0.1 • Repeatability ±0.2 • Reproducibility ±0.5|
|Measurement range: 0-100|
|REFLECTANCE 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 reflective 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.|
