Description
Overview
GAOTek Analyzer Nitrate Ion Meter NO3 absorbs at 210nm ultraviolet light. When the probe is working, the water sample flows through the slit. When the light emitted by 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 for detection, to calculate the concentration of nitrate.
