PUVNO3-900 China Wholesale Factory Spectrometer Online Nitrate Nitrogen Analyzer Sensor And Transmitter Nitrate NO3 Water Quality Testing

n  Measurement Principle

NO3 absorbs at 210 nm UV light. When the Spectrometer NO3 probe is working, the water sample flows through the slit. When the light from the light source in the probe passes through the slit, part of the light is absorbed by the sample flowing in the slit, and the other light passes through the sample and reaches the other side of the probe. Calculate the concentration of nitrate.
