Product Description

OHSP-350A Luminous flux Version, Cancelled the illuminance (LX) parameters and add the luminous flux (LM) parameters on the basis of the quintessence, MD8 interface, with 485 communication functions.

Measuring Parameters

1. CCT Tc (K) and blackbody deviating Duv.
2.Luminous flux (LM), radiation flux (W) and light effect (lm/W). 
(need to manually enter the light source power when using machine).
3. chromaticity coordinates (x, y), (U, V), (U ', V').
4. relative spectral power distribution P (lambda).
5. color rendering index Ra, Ri (i=1 ~ 15).
6. color tolerance (SDCM, CIE and Macadam rectangle u 'V' round).
7. Dominant wavelengths, peak wavelengths.
8. light and dark visual ratio S/P.
9. color purity, red ratio, green ratio, blue ratio, CIE1931 three basic color stimulus value X, Y, Z.
10. more functional parameters can be customized.
