Rhopoint IQ 20/60/85 Gloss, Haze and DOI Surface Appearance Meter
Gloss at 20°, 60° and 85° with reflection haze, distinctness of image (DOI) and RIQ, quantifying the appearance quality of paint, coating, plastic and metal surfaces.
In short
Gloss at 20°, 60° and 85° with reflection haze, distinctness of image (DOI) and RIQ, quantifying the appearance quality of paint, coating, plastic and metal surfaces. The Rhopoint IQ 20/60/85 combines the three standard geometries of a conventional glossmeter (20°, 60°, 85°) with a high-resolution linear diode array detector that records the full profile of the reflected light.

Overview
The Rhopoint IQ 20/60/85 combines the three standard geometries of a conventional glossmeter (20°, 60°, 85°) with a high-resolution linear diode array detector that records the full profile of the reflected light. From this profile a single measurement yields gloss units (GU) together with reflection haze (HU), distinctness of image (DOI), reflected image quality (RIQ) and peak reflectance, distinguishing surfaces of equal gloss that are perceived differently (orange peel, milky haze, micro-texture). The instrument supports gloss measurement to ISO 2813 and ASTM D523, haze to ASTM E430 and ISO 13803, and DOI to ASTM D5767. It is used for quality control, supplier conformity and product development on automotive paint and clearcoats, powder coatings, coil coatings, polymer parts, polished metal, glass and printed surfaces. Readings are stored with statistics, and traceability is maintained through the reference calibration tile.
