Digital RS485 Optical Nitrate Nitrogen Sensor NO3-N
Principle
NO3 has an absorption at 210nm ultraviolet light. During operation, the sample flows through the slit, and the light emitted by the light source passes through the slit. Some of the light is absorbed by the moving sample in the slit, while the rest of the light passes through the sample and reaches the detector on the other side of the probe, where the nitrate concentration value is calculated. -
