The Rhopoint IQ-S is the ultimate glossmeter upgrade 

The Rhopoint IQ-S was specially designed and built to match automotive interior gloss measurement standards. IQ-S gloss measurements are fully compatible with existing Micro-TRI-gloss-S results.

All IQ-S are close tolerance selected for maximum accuracy and comparability in all gloss applications. 

The Rhopoint IQ-S not only measures gloss but also measures image quality and profiles how light is reflected from a surface. Standard glossmeters only measure how much light is reflected and are not sensitive to effects which dramatically reduce appearance quality.

The Rhopoint IQ-S measures

20/60/85° Gloss • Haze • Distinctness of image • Rspec • Goniophotometric curves

GLOSS

A measurement proportional to the amount of light reflected specularly from a surface.
Geometry: For best results the correct measurement geometry should be chosen based on the reflectance of the material: Matt Finish 85°, Mid Gloss 60°, High Gloss and Metallics 20°.
Measurement Unit: GU

RSPEC

The peak gloss value over a very narrow angle.
Usage – RSPEC is very sensitive to small changes in texture and is used to identify subtle differences in surface smoothness.
Measurement Unit: GU

REFLECTANCE HAZE

An optical effect caused by microscopic textures or residue on a surface.
Visible Symptoms: milky finish apparent on surface, loss of reflected contrast, halos and patterns can be seen around reflections of high intensity light sources on high gloss and metallic samples/mirrors.
Causes: Poor dispersion, raw material incompatibility, additive migration, vehicle quality, stoving/drying/curing conditions, polishing marks, fine scrat¬ches, ageing, oxidisation, poor cleanliness/surface residue.
Measurement Unit: LogHU

DISTINCTNESS OF IMAGE

A measure of how clearly a reflected image will appear in a reflective surface.
Symptoms of poor DOI: 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.
Measurement Scale: 0-100, with 100 being a perfect smooth surface.

REFLECTED IMAGE QUALITY (RIQ) 

Like the DOI the RIQ value describes the quality of a surface in terms of how clearly visible an image is reflected.
Unlike the DOI the RIQ uses a much larger resolution that results in a much better correlation to the visual perception of the human eye. This is of a very high importance for high quality surfaces like e.g. car coatings.
Measurement Scale: 0-100, with 100 being a perfect smooth surface

GONIOPHOTOMETRIC PROFILE

The instrument displays surface reflectance profiles 17-23° (larger range with software). 
The shape of the curve describes how the light has interacted with the surface.
Sharp curves close to the specular direction indicate smooth highly reflective surfaces.

An on screen goniophotometric profile shows the distribution of the reflected light.

Different textures and distortions produce identifiably shaped profiles depending on their size and frequency. Full goniophotometric information can be downloaded to PC for further analysis and comparison, without the need for interface software.

The Novo-Gloss 20/60/85° gloss meter is designed to meet the measurement criteria for most gloss measuring applications.

The Novo-Gloss Trio low cost glossmeter is ideal for gloss measurements of all surfaces and is suitable for matt to mirror gloss surfaces

The Novo-Gloss 60 degree gloss meter is suitable for measuring gloss in most applications from matt to high gloss finishes.

The Novo-Gloss Dualgloss gloss-meter is perfect for basic gloss measurement and is best suited for mid to mirror gloss surfaces (10+ GU @60°)

Designed specifically to measure the gloss of surfaces that cannot be measured using traditional gloss-meters, the Novo-Gloss Flex 60 gloss-meter combines the functionality and reporting of an advanced gloss-meter with an ultra lightweight remote measuring head.

The Novo-Curve glossmeter is a unique instrument with specially designed optics for accurately measuring curved surfaces and small areas. It can also be used to measure flat surfaces and areas which are too small to measure with standard glossmeters.
