The 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 other effects which reduce appearance quality.

The Concrete Clarity Meter (CCM) can measure

  • 20/60° Gloss
  • RSPEC
  • Reflectance haze
  • Reflected image quality (RIQ)
  • Distinctness of Image (DOI)

Unlike a standard glossmeter the IQ Concrete Clarity Meter has the unique capability of measuring and detecting
quality problems caused by microscopic texture in the surface that cause haze and orange-peel effects which lead to poor Distinctness of Image (DOI).


These factors can seriously affect the visual impact and reflective quality of many coated, painted and polished
surfaces. By measuring the quality of the reflected image it accurately profiles how light is reflected from a surface.

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.

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

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.

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.

Causes: Resin transfer, lack of refinement, burnish
and polishing marks, fine scratches, poor cleanliness/surface residue.

Reflectance Haze

DOI is the sharpness of images of objects produced by reflection at a polished surface, sometimes called image clarity.

Measurement by Image Clarity Meter: 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).

Reflectance Haze

Haze is the cloudiness or milky appearance of images of objects produced by reflection in a polished surface.

Measurement by Glossmeter (ASTM D4039): The Haze Index, obtained from this test method, is computed using the numeric difference between the value of specular gloss at 60° and the value of specular gloss at 20°.

Measurements for Compliance

The Image Clarity Meter and Glossmeter must be calibrated.
The minimum number of tests distributed across the polished surface should be three for areas up to 1000ft² and one additional test for each 1000ft² or fraction thereof. This applies to both the Image Clarity Value and Haze Index.
The mean (average) values of the test results should be used to evaluate compliance with the chart.
