EVERFINE spectral color BM-9 color luminance meter

product description

Color filter method fitting, spectral curve, and good telephoto objective lens with high image quality can be used to measure the brightness, chromaticity coordinates, color temperature, and color difference of distant objects or light sources point by point. Because the color filter method has the problem of spectral mismatch error, it seriously affects the accuracy of brightness and color testing.

Application Guide

BM-9 color luminance meter is widely used in: brightness testing of indicator lights, instrument panels, landscape lighting, road and bridge projects, traffic lights, car lights, etc. Especially suitable for: large LED displays, large LCD displays, plasma screens, projectors, OLED, backlights and other large displays.

Technical indicators
