The BGD 582 Opacity Meter is our latest next-generation product, designed with a 45°/0° optical geometry (45° annular uniform illumination, 0° reception) to comply with ISO 6504-3 “Paints and varnishes—Determination of hiding power—Part 3: Determination of contrast ratio of light-coloured paints at a fixed spreading rate.” and ASTM D2805-21 ”Standard Test Method for Hiding Power of Paits byReflectometry”
     Additionally, it automatically calculates the contrast ratio (C = Rb/Rw) of samples.
