Chroma Light Meter ST520 Temperature Brightness Luminance LED Lamps Color Tester

Description

SENTRY ST520 Chroma Light Meter light luminance and color coordinate Illuminance color temperature tester
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
