LS3600 Oil-in-Water Analyzer

Instrument Principle:

When monochromatic light passes through the measured solution, its energy is absorbed. The intensity of light absorption is proportional to the concentration of the measured substance, in accordance with the Lambert-Beer law: A=log(1/T)=log(I0/I)=a×b×c
