Description
Overview
GAOTek Color difference Meter Colorimeter can measure the color Temperature, Illuminance, Chromaticity, Excitation Purity, Luminous Flux, RGB and Dominant Wavelength of various light sources. Model CLM-200H exclusively does this under LED, Organic LED (OLED), and other forms of Organic Electroluminescence (EL). When determining the accuracy of an LE illumination, color temperature measurements are particularly important. This instrument utilizes sensors that closely parallel the color-matching functions specified by the International Commission on Illumination (CIE). Depending on the application for which the instrument is being used, results can be displayed through different color notations.
