SENTRY ST520 Chroma Light Meter Light Luminance Meter for Color LED Lighting

SENTRY ST520 Chroma Light Meter Light Luminance Meter for Color LED Lighting(PLEASE NOTE THAT SHIPPING IS DELAYED UNTIL MAY 15, 2023 AS WE ARE OUT OF THE COUNTRY)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:

1.Precision instrument for light luminance and color coordinate
5.Lux or foot-candle unit selection

Illuminance: Ev (lx or fcd)

Color Coordinate: (x,y), (u\\\\\\\',v\\\\\\\') (CIE 1960)

Correlated Color Temperature: CT, uv

Color Difference:(Ev,x,y), (Ev,u\\\\\\\',v\\\\\\\'), (Ev,u\\\\\\\'v\\\\\\\'), (One set of reference color)
