Rhopoint FLEX 20-S with its remote head Glossmeter effective to measure surface quality on curved surfaces and difficult to reach areas

The Rhopoint IQ FLEX 20-S units are the ultimate glossmeters for small parts

Like the Rhopoint IQ-S, the Rhopoint IQ FLEX 20-S measures 20-degree gloss and profiles how light is reflected from a surface. Standard gloss meters only measure how much light is reflected and are not sensitive to effects which dramatically reduce appearance quality.

The Rhopoint IQ FLEX 20-S is specifically designed for difficult surfaces or small parts. The small footprint of the IQ FLEX 20-S sensor makes it much more effective on curved surfaces and difficult-to-reach areas than a conventional gloss meter.

IQ FLEX measurements are fully compatible with existing Rhopoint IQ-S gloss and appearance data.

For improved performance and repeatability on even the smallest parts, the Rhopoint IQ FLEX 20-S can be customised with magnetically attached adaptor plates. Using 3D printing technology, it is possible to create custom measuring jigs from the CAD diagrams of your components. These adaptors can be easily interchanged for different applications as required.

The Rhopoint IQ FLEX 20-S has been designed for maximum adaptability and can use non-contact plates for in-line applications or with adaptors of rubber, felt or plastic for delicate surfaces.

  • IQ appearance values: measures gloss, surface haze, distinctness of image, Rspec and goniophotometric curves, providing more complete data on surface appearance in a single measurement.
  • Developed for accuracy in difficult applications: 4 & 2mm spot sizes and small footprint measuring head facilitates the easy measurement of small parts and curved surfaces.
  • Customisable: The measurement head can be customised with magnetically attached adaptor plates 3D printed to aid positioning and repeatability.
  • User friendly data: measurement data is displayed on the built in back-lit display and can be simultaneously transmitted via USB or Bluetooth to Microsoft Excel for storage, analysis or reporting.
