Rhopoint - DOI (Orange Peel) Gloss & Haze - Rhopoint IQ Flex 20
| Previous | 3 / 36 | Next |
- Designed for the measurement of small and curved surfaces
- DOI / RIQ Meter, (quantify orange peel)
- Hazemeter (reflectance haze)
- Custom adaptors for the measurement of non-flat surfaces
The Rhopoint IQ Flex 20 quantifies surface quality problems such as orange and peel and haze that are invisible to a standard glossmeter and profiles how light is reflected from a surface.
Previously only available for measuring flat surfaces, this technology is now available in a new format specifically designed for curved surfaces and small & delicate parts.
This incredibly advanced instrument measures:
20° GLOSS • HAZE• REFLECTED IMAGE QUALITY (RIQ) • DISTINCTNESS OF IMAGE (DOI) • RSPEC
In practice, these terms mean:
Gloss: A measurement proportional to the amount of light reflected from a surface measured at 20° (high gloss)
Haze: An optical effect caused by microscopic textures or residue on a surface.
RIQ : Used to quantify effects such as orange peel and surface waviness. This new parameter gives higher resolution results compared to Distinctness of Image (DOI)
measurement and better mimics human perception of surface texture, especially on high quality finishes such as automotive paint finish.
DOI: A measure of how clearly a reflected image will appear in a reflective surface.
RSPEC: The peak gloss value over a very narrow angle.
Features:
- Compact measuring head enables curved surfaces and small areas to be measured easily
- Interchangeable magnetic adaptors allow reduced measurement spot sizes down to 4mm or 2mm
- Bespoke 3D printed adaptor jigs available for repeatable sample positioning
- Alternative rubber, felt or plastic adaptors can be specified for delicate surfaces
- Non-contact adaptor plates allow the measurement head to be fixed above moving products on line or robotised
- Single button push to measure all parameters for easy identification of non-conformances
- Onboard Statistics (max, min, mean, S.D.) and graphs
- Results batching with user definable names
- Rhopoint Data Widget – Allows results to be instantly transmitted to any PC package such as Excel, Word, SPC programs etc.
- Bluetooth Compatibility – transmit data to any smartphone, tablet or PC
- USB results download to PC without the need to install software
