Rhopoint IQ 20°/60°/85° Goniophotometer
The Ultimate Glossmeter Upgrade.
The Rhopoint IQ 20/60/85 Gloss Haze DOI Meter is an advanced measuring instrument used to quantify the quality of surface appearance. Unlike a standard glossmeter, the IQ has the unique capability of measuring and detecting quality problems caused by microscopic texture in the surface that cause haze. Here are some key features of the Rhopoint IQ:
- Gloss Measurement: The Rhopoint IQ can measure gloss at three different angles: 20°, 60°, and 85°. These angles cover a range from matt to mirror finishes.
- Haze Measurement: It quantifies the amount of haze present on a surface, which can affect visual clarity.
- DOI (Distinctness of Image) Measurement: This parameter assesses how clearly a reflected image appears in a reflective surface. It’s crucial for evaluating appearance quality, especially in high-quality finishes like automotive coatings.
- RIQ (Reflected Image Quality) Measurement: RIQ helps quantify effects such as orange peel, brush marks, and waviness. It provides higher resolution results compared to DOI measurement and mimics human perception of surface texture.
Standards Compliance
- Gloss – ISO 2813, ISO 7668, ASTM D523, ASTM D2457, DIN 67530, JIS Z 8741 and JIS K 5600-4-7
- Haze – ASTM E430 and ASTM 13803
- DOI – ASTM E430
In summary, the Rhopoint IQ goes beyond traditional gloss measurements, allowing you to identify subtle surface quality issues that might be invisible to standard glossmeters. Whether you’re in the automotive, furniture, coatings, or other industries, the Rhopoint IQ provides valuable insights into surface appearance and quality. Contact us for demonstration
