UVN Nitrate Nitrogen Analyzer

Operating Principle

The nitrate analyzer adopts high-precision ultraviolet (UV) absorption technology. During measurement, the sample fills the optical path. Light emitted from the source passes through the water sample, where part of the light is absorbed. The remaining light is detected by a sensor on the opposite side. The analyzer calculates the nitrate nitrogen concentration based on the absorption characteristics.

Product Application
