Rhopoint IQ Flex 60

  • Measure small footprint areas
  • Measure curved and hard to reach surfaces

Designed specifically to measure the gloss of surfaces that cannot be measured using standard glossmeters, the Novo-Gloss Flex 60 Glossmeter combines the features of a standard meter with an ultra lightweight remote measuring head.

The Rhopoint IQ Flex 60 Gloss, DOI, Haze and RSPEC Meter has all the features of a standard Rhopoint IQ but with the ability to measure small and slightly curved surfaces.

  • Designed for the measurement of small and slightly curved sufaces
  • DOI / RIQ Meter, ( quantifies orange peel )
  • Hazemeter ( reflectance haze )
  • Measures RSPEC
  • 60° glossmeter for general gloss finishes

In a single fast measurement, the Rhopoint IQ Flex 60 captures information about the gloss and texture of a sample surface. 
Combined gloss, haze, and orange peel (DOI/RIQ values) information have made the IQ essential for controlling appearance finish in the paints and coatings sector, particularly for high tech., automotive and aerospace coatings.

Designed for slightly curved surfaces

Conventional gloss instruments are best suited to large flat areas and test panels, as curved surfaces cause measurement errors. The small footprint of the Rhopoint IQ Flex 60 makes it much more effective on curved surfaces than a conventional glossmeter; its compact size and shape also allows access to difficult to reach areas

The Rhopoint IQ Flex 60 quantifies surface quality problems that are invisible to a standard glossmeter

The Rhopoint IQ Flex 60 goes beyond gloss measurement by differentiating between two samples with EQUAL GLOSS VALUES. This is achieved by measuring the image quality (is it like a mirror), it is the only handheld instrument that profiles how light is reflected from a surface, thus presenting you with the easily understood information to show you the better sample being measured.

Standard glossmeters only measure how much light is reflected and are not sensitive to effects which dramatically reduce appearance quality. The Rhopoint IQ Flex 60 DOI "Distinctness of Image" Quality Meter easily accomplishes the measurement of appearance. Information is displayed with one value, not multiple confusing values, but immediately and easily seen.

The Rhopoint IQ Flex 60 Measures

  • 60° Gloss
  • Haze
  • Distinctness of Image - DOI
  • RIQ

What is DOI ?

DOI, Distinctness of Image, is a measurement indicating the QUALITY OF THE GLOSS. How clearly can a reflected image appear.

Symptoms of poor DOI: Orange peel, brush marks, waviness or other structures visible on the surface. Poor finishing. 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.

What is RSPEC ?

RSPEC is the peak gloss value over a very narrow-angle.
RSPEC is very sensitive to small changes in texture and is used to identify subtle differences in surface smoothness.

What is RIQ ?

RIQ is a superior measurement to DOI with expanded capabilities.RIQ quantifies ORANGE PEEL qualitatively as well as measuring surface waviness. RIQ is a HIGH-RESOLUTION DOI measurement and correlates better with human vision and perception.

Orange Peel, brush marks, waviness, cause reflected images to be distorted.

Problems that can be detected using the Rhopoint IQ Flex 60 include:

  • Incorrect Coating Flow
  • Coating Viscosity
  • Sag or Coating Flow before Curing
  • Particle Size Distribution
  • Paint Overspray
  • Improper Flash, Recoat Time
  • Inter Coat Compatability
  • Incorrect Cure Time
  • Cure Temperature

Reflectance Haze with the Rhopoint IQ Flex 60

Reflectance Haze is an optical effect caused by microscopic texture or residue on a surface. A milky finish is apparent on the surface causing a loss of reflected contrast, halos and patterns can be seen around reflections of high-intensity light sources.

Causes: Poor dispersion, raw material incompatibility, additive migration, vehicle quality, stoving/drying/curing conditions, polishing marks, fine scratches, aging, oxidization, poor cleanliness/surface residue.


A measurement proportional to the amount of light reflected from a surface.

Geometry: For best results the correct measurement geometry should be chosen based on the reflectance of the material. 60° is the ideal angle to measure general gloss surfaces.


Goniphotometric Profiles

Printed Material

The instrument displays surface reflectance profiles 57-62°. 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.
