Rhopoint IQ Goniophotometer, DOI Meter, Hazemeter and 20′/60′ or 20′/60′/85′ Glossmeter

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

The Rhopoint IQ measures image quality – It is the only hand-held instrument that 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.

Whilst glossmeters are widely used throughout industry to assess the reflective qualities of products, gloss information alone is limited as it tells us how much light is reflected, but nothing about the imaging forming qualities of a surface.

Phenomena such orange peel, haze effects and polishing marks distort reflections in a surface, seriously reducing visual appearance but cannot be measured with a traditional glossmeter. This means two surfaces which have very different reflective properties often have exactly the same gloss value.

The New Rhopoint IQ can measure all aspects of Reflective appearance quality. The Rhopoint IQ measures GLOSS, HAZE and Distinctness of Image – Complete reflective appearance analysis in a single reading, allowing you to quantify and control the surface textures that reduce the perceived quality of manufactured products.

Paints and coatings manufacturers and applicators, wood coatings, automotive industry, plastics and additives manufacturers, inks and printing, metal polishers, coil coaters, yacht manufacturers and powder coaters are amongst the many industries that are currently assessing surface quality using Rhopoint IQ technology.

The unique all aluminium construction of the Rhopoint IQ provides strength and rigidity in the instrument providing you with improved accuracy and reliability over previous generations of gloss instruments. A full colour, high definition screen and five way touch sensitive buttons make the instrument incredibly easy for you to read and operate.

The features of the Rhopoint IQ can be switched on and off independently – the instrument can be configured as a fully functional 20/60/85° Gloss-Haze-DOI-Goniophotometer with memory or as a simple single, dual or triple angle non-statistical glossmeter.

Each Rhopoint IQ instrument is supplied with an ISO 17025 laboratory calibrated standard with detailed traceability to BAM and stated uncertainty. This high level of traceability is required for automotive, defence, pharmaceutical and other similar applications.

The Rhopoint IQ displays statistics for all measured parameters – It also displays full colour trend graphs on the instrument screen giving you a detailed understanding of the sample quality without the need to download results to a spreadsheet.

Results from the Rhopoint IQ can be imported directly to a PC/MAC without downloading or installing any special software – Plug the instrument into any computer and the onboard memory is accessed like a USB drive. Results are stored as industry-standard CSV files that can be displayed in spreadsheet programs such as Excel.

Rhopoint Novo-Shade Duo+ Reflectometer

The Novo-Shade Duo+ is a portable 45/0° reflectometer that can be used to assess either the shade of a surface (a simple indication of colour based on lightness/darkness) or calculate the opacity of a coating, plastic film or paper sample.

Measuring using 0/45º, the Novo-Shade Duo+ measures the colour of a surface and not the specular reflectance (gloss). In Shade Mode the Novo-Shade Duo can help maintain the production quality of the following:

Shade of paints, inks and coatings

Fading of textiles and plastics

Chalking of paint

Efficiency of detergents and bleaching agents

Whiteness of recycled paper

Cleanliness and oxidisation on metal surfaces

Substantial savings can be achieved by accurately measuring the hiding power of a coating formulation. It is often possible to reduce the amount of expensive opacity modifying agents in the coating whilst maintaining the required hiding power. Even marginal reductions in raw materials such as Titanium Dioxide can add up to significant savings over several batches of product.

Measuring the opacity of printed flexible packaging can also lead to cost savings for the printer. The applied film weight of an opaque coating can often be reduced by 20% whilst maintaining the hiding power required in the finished film.

The Rhopoint Novo-Shade Duo+ is a dual function reflectometer that can accurately measure these values.

The instrument has all the features found in the Novo-Gloss range:

  • Full colour, easy to read display
  • On-board statistics and graphs  (in shade mode only)
  • Touch sensitive keypad
  • USB results download to your PC.
  • Bluetooth connectivity
  • Battery recharge by either USB or mains supply

Rhopoint PAINTLAB+ Krebs Viscometer

The Rhopoint Instruments PAINTLAB+ Krebs Viscometer offers you high accuracy viscosity measurement with advanced functionality.

Conforming to ASTM D562, the PAINTLAB+ Krebs Viscometer uses a rotating paddle to directly measure the viscosity in Krebs units (KU), centipoise (cP) or grams (g). All three measurement units are shown on the screen simultaneously after your test.

You can monitor changes during the measurement to provide identification of inconsistencies between samples.

As viscosity of coatings is temperature dependent, it is essential that temperature of the sample is controlled and known at the time of measurement. The Rhopoint Krebs Viscometer is the only instrument that is supplied with built-in calibrated temperature measurement and temperature is recorded before and after the test is run.

The fully automated operation of the PAINTLAB+ Krebs Viscometer saves you time by accurately lowering the paddle into the sample to the correct height for a number of standard container sizes. Once the test is complete, the paddle automatically raises to drain off, again saving time needed for cleaning.

The lab-tough glass touch screen can be cleaned with any solvent or scraped with scalpel to ‘as new’ condition after testing. The all aluminium construction, lab-tough nylon fixings and neoprene sample mat means that the entire instrument can be cleaned with strong solvents, including MEK and acetone.

Rhopoint PAINTLAB+ Cone & Plate Viscometer

The Rhopoint PAINTLAB+ Cone & Plate Viscometer provides you with high accuracy viscosity measurement of non-Newtonian paints and coatings.

Conforming to BS 3900 A7, ASTM D 4287 and ISO 2884, the PAINTLAB+ Cone & Plate Viscometer’s high stability motor speed control ensures accuracy and repeatability during each test.

Real-time high resolution graphing allows you to monitor changes during measurement, providing identification of inconsistencies between samples.

Measurement results are displayed instantly on screen after test in P, cP, Pa.s or mPa.s.

The PAINTLAB+ Cone & Plate Viscometer incorporates an integrated, high stability temperature controlled plate onto which the samples to be tested are applied.

A preheat function allows rapid stabilisation of the sample temperature, which is accurately controlled during the measurement process.

You can print the test results in P, cP, Pa.s or mPa.s. immediately on a time and date stamped results label, which also gives temperature before and after testing.

Lab-tough glass touch screen can be cleaned with any solvent or scraped with scalpel to an ‘as new’ condition. An all aluminium construction, with lab-tough nylon fixings and a neoprene sample mat mean that you can clean the entire instrument with strong solvents, including MEK and acetone.

Rhopoint PAINTLAB+ Pfund Cryptometer

The Rhopoint Instruments PAINTLAB+ Pfund Cryptometer is a wedge type film applicator that enables the determination of the wet hiding power of a coating within a few minutes.

This simple and accurate test of wet film hiding power enables you to determine the coating thickness needed for complete opacity, and gives an estimate of the coating coverage (spreading power) in square metres per litre.

This is required by some product specifications and national test methods which accept the limitations that it is the wet film, and not the dry coating, that is being measured.
