Product Description

ST520 is a chroma meter with precision measurement of light luminance and color coordinate. It meets CIE photopic spectral response and the color temperature is given to verify the light source. Correlated color temperature and custom reference value of color difference mode are useful for users to measure and identify the differences between light sources.
