Description

The Rhopoint IQ Gloss Haze & DOI Meter measures surface quality problems that are unseen by an average glossmeter and outlines how light is reflected from a surface. The Rhopoint IQ Goniophotometer instrument measures the following parameters in a click of a button.

20/60/85° GLOSS • HAZE• REFLECTED IMAGE QUALITY (RIQ) • DISTINCTNESS OF IMAGE (DOI) • RSPEC 

Gloss: This is a measurement proportional to the amount of light reflected from a surface at 20° for high gloss finishes, 60° if a surface has a mid-gloss finish and 85° for matt finishes.

Haze: Reflection haze is a scattered light that is caused by micro texture. It is measured adjacent to the main gloss component. The symptoms include a milky finish which can be seen on high gloss finishes and halos may be visible around reflections of bright light sources. On the other hand the causes may be dispersion problems, raw material incompatibilities, incorrect curing, cleanliness, ageing, oxidisation, scratching or polishing.

RIQ: RIQ can be used to measure the effects for example orange peel and surface waviness. Providing higher resolution results compared to distinctiveness of image measurement and better mimics of human perception or surface texture, especially on high quality finishes including automotive is this new parameter. Some of the symptoms of poor RIQ may include orange peel, brush marks, waviness or any other structures visible on the surface of the item. The causes of these could be application problems, incorrect coating flow, incorrect cure times, coating viscosity being too high or low, sag of coating before curing , the incorrect particle size, overspray and cure temperature.

DOI: DOI is the distinctiveness of image and is a measurement of how visible a reflected image will look in a reflective surface.

RSPEC: This is the peak gloss value over an extremely narrow angle.

Features:

  • The brightness is adjustable and has a full color screen that is easy to read
  • Touch sensitive 6 button interface
  • Error free, fully automatic calibration that has verification and tile detection
  • Instrument that is pocket sized and comes with a combined tile holder
  • Easy identification as the whether the item has passed or failed
  • Full on board statics including min, max and mean etc.
  • Trend analysis graph(s)
  • Results which batch with user names
  • Input data direct through Bluetooth – This allows each and every reading to be immediately transmitted to any computer package such as excel or word
  • Software free data transfer – USB download of results to computer ( no software installation needed)

THE ULTIMATE GLOSSMETER UPGRADE

The Rhopoint IQ Goniophotometer Gloss Haze & DOI Meter calculates surface quality complications that are undetectable to a typical glossmeter. It is the only hand held instrument that is able to measure the reflected image quality and how light is reflected from a surface. In addition to this, gloss meters are used to measure ‘shininess’ of a surface however they aren’t sensitive to common effects.

Rhopoint Iq Orange Peel Panel

The appearance quality is dramatically reduced due to orange peel without affecting gloss readings. Both of these two test panels measure identically with a normal glossmeter however the Rhopoint IQ with RIQ/DOI measurement can quantify the differences.

Haze is a regular problem related with the coatings and polished materials. Any haze surface will have a ‘milky’ finish with a shallow reflected image. This characteristic is directly measured with the Rhopoint IQ.

GLOSS

Gloss is a measurement which is proportional to the amount of light reflected from a surface.

Geometry: The accurate measurement geometry should be used according to the sample finish – 20° for high gloss finishes, 60° if a surface has a mid-gloss finish and 85° for matt finishes.

RSPEC

RSPEC is the peak gloss that is measured over an extremely narrow angle. The usage includes it being very sensitive to surface texture and also can be used to identify subtle different in surfaces that are smooth.

REFLECTANCE HAZE

Reflectance haze is an optical effect caused by microscopic texture or residue on a particular surface. The visible symptoms include a milky finish which is apparent on the surface with a loss of reflected contrast. Also halos and patterns may be seen around the reflections of high intensity light sources. The causes of this may include factors such as addictive migration, vehicle quality, poor dispersion, fine scratches, oxidisation and surface residue.

REFLECTANCE HAZE COMPENSATION

The instrument reimburses for reflection from within the coating for highly reflective pigments, speciality pigments and metallic coatings, allowing the haze of any painted surface to be measured.

REFLECTED IMAGE QUALITY (RIQ)

Reflected image quality is also known as RIQ and is used to quantify effects including orange peel and surface waviness. This parameter allows a higher resolution results compared to distinctness of image measurement and improved mimics human perception of surface texture, especially on high quality finishes including automotive. The symptoms of poor reflected image quality include brush marks or other structures that appear on the surface. The causes of this can include application problems, incorrect coating flow, improper flash/ recoat time, incorrect particle size, inter coat compatibility, cure temperature and incorrect cure times.

DISTINCTNESS OF IMAGE (DOI)

The distinctness of image is a measurement of how clear a reflected image will appear on a reflective surface.

Measurement

gloss haze DOI screen

It offers a fast measurement of all parameters with full on board statics with graphical trend analysis and reporting.

Simultaneous calculations of all parameters and the results given are all date and time stamped.

Rhopoint IQ gloss haze graph

It displays full statistics for the number of readings in the batch.

Graphical reporting for fast trend analysis.

orange peel meter pass fail

For instant identification of non-conformances a pass or fail parameter can be defined.

Goniophotometric Curves

Different kinds of surface textures can produce identifiably shaped reflectance profile. The data given can then be downloaded to a computer for further analysis and comparison if needed via either the USB cable or Bluetooth data widget.

Easy Batching

For more efficient and quicker reporting, it offers user definable batch names and sizes.

Rapid data transfer Software-free data transfer.

The USB connection into a computer will allow the device to be recognised and will then transfer the files using Windows or another platform.

Direct data input via Bluetooth

This device instantly transmits measured readings directly to programs such as Microsoft Excel to help you simplify the reporting process.
