RHOPOINT IQ Surface Optical Detector - Gloss, Fog Shadow, Brightness, Peak Reflectance, Imaging Quality

RHOPOINT IQ can measure gloss at 20 degrees, 60 degrees, and 20/60/85

Can measure freshness

Can measure fog shadows

Industries in which the improved gloss meter is applied:

Paint and coating manufacturers and suppliers, wood coatings, automotive industry, plastic and additive manufacturers, ink, printing, metal polishing machines, coil coating machines, yacht manufacturers, and powder coating machines are currently using Rhopoint IQ surface quality assessment technology.

·RHOPOINT IQ is the upgraded version of the gloss meter.

·IQ is compatible with both small gloss meters and triangular gloss meters.

RHOPOINT IQ

RHOPOINT IQ is a handheld instrument for measuring surface optical quality, which describes how light is reflected from the surface of an object. However, traditional gloss meters can only measure the amount of reflected light and are not sensitive to the impact on appearance quality.

Surface texture can weaken the quality of surface imaging without affecting glossiness values. The two panels above obtained the same data using a traditional gloss meter.

RHOPOINT IQ

It can measure gloss, haze, clarity, peak reflectance, and gloss meter curves at 20 °/60 °/85 °.

Gloss analysis-Measure the light reflected from the surface of an object proportionally.

Geometric analysis: In order to obtain good measurement results, the correct geometric measurement should be based on object reflection: 85? Yaguang, 60? Medium gloss, high gloss, and 20? The metallic color.

Measurement unit: GU

peak reflectivity-It is an indicator that characterizes the intensity of light within a small angle range from the reflection angle.

Usage: Peak reflectance is very sensitive to subtle changes in texture and is used to distinguish subtle differences in surface smoothness.

Measurement unit: GU

Reflection fog shadow-An optical effect caused by surface residues or fine textures.

Visible phenomena: surface emulsions, loss of reflection contrast, foggy images, etc. can all be seen in the reflection images of high-intensity light sources.

Reasons: poor dispersibility, incompatibility of raw materials, migration of additives, quality of media, drying/curing, polishing marks, minor scratches, aging, oxidation, insufficient cleanliness, and surface residues.

Measurement unit: LogHU

doi-How to obtain clear reflection images on the surface.

The phenomenon of low value freshness: orange peel, markings brushed on the surface, ripples or other visible structures. Causing distortion of the reflected image.

Causes: Application issues, incorrect coating flow, coating viscosity too high or too low, depression or flow of coating before curing, incorrect particle size or distribution, overspray, inappropriate irradiation or re spraying time, compatibility between coatings, incorrect correction time or temperature.

Measurement mode: 0-100100 is a smooth surface with *.

Mirror glossiness-The instrument displays a reflective surface with a surface angle of 17-23 °. The shape of the curve in the figure describes the mutual influence between light and surface. The sharp turn of the curve approaching the mirror surface indicates a smooth and highly reflective surface.

The above is a description of the glossiness displayed on the screen, showing the distribution of reflected light.

The graph on the above screen displays the trend of the measurement results.

Different textures and distortions result in recognizable side shadows based on their own size and frequency. The complete gloss information can be downloaded to a computer for further analysis and comparison without the need for conversion software.
