Nitrate Nitrogen
UVN Nitrate Nitrogen Analyzer
Nitrate Nitrogen
Reagent-free UV absorption nitrate analyzer with second-level response — in-situ immersion measurement that gives denitrification and carbon dosing systems the real-time feedback they need.
- Second-level response enables true closed-loop dosing control
- Zero reagents and zero consumables — minimal operating cost
- Direct immersion in the tank or filter — no sampling system required
- Interlocked carbon dosing measurably cuts chemical consumption
Overview
A nitrate nitrogen analyzer continuously measures the NO₃⁻-N concentration in water. In wastewater treatment it provides the real-time feedback required to control denitrification and optimize carbon source dosing; in effluent monitoring it verifies nitrogen compliance.
The UVN Nitrate Nitrogen 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, and the analyzer calculates the nitrate nitrogen concentration based on the absorption characteristics, with compensation for turbidity and organic interference.
