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.

Features

Precision instrument for light luminance and color coordinate

Meet CIE (International Commission on Illumination) photopic spectral response

Color temperature or Correlated color temperature

Custom reference value of color difference mode

Lux or foot-candle unit selection

Magnetic mount

Tripod socket
