Lumen Test Spectrometer (Full Function)

OHSP-350 M Lumen Spectrometer , it can test Lux and Luminous flux in one, Suitable for measuring the luminous flux of single light source or whole LED lamp. Also good for field test .

It also can match a big sphere for Lumen test .

Meas parameters Wave range:350-950nm
