SLDW1110 Series Ion-Selective Electrode (ISE) Ammonia Nitrogen Analyzer
Professional Water Quality Monitoring Solution for Industrial & Environmental Applications
Product Overview
The SLDW1110 Series Ammonia Nitrogen Analyzer is a cutting-edge water quality monitoring device designed to accurately measure ammonia nitrogen (NH₄⁺-N) concentration in aqueous environments. Leveraging the ion-selective electrode (ISE) technology, it integrates multi-sensor synergy, rapid response, and eco-friendly operation-addressing the pain points of traditional colorimetric methods (e.g., Nessler's method, salicylate method) such as slow speed and hazardous waste generation. Ideal for industrial wastewater treatment, municipal sewage plants, surface water monitoring, and drinking water sources, it ensures real-time, reliable data to support compliance and environmental protection.
Working Principle
At the core of the SLDW1110 is the ion-selective electrode method: its built-in ammonium ion-selective electrode directly detects ammonium ions (NH₄⁺) in water to determine ammonia nitrogen concentration, while a pH electrode acts as a reference to enhance measurement stability . Additionally, a temperature electrode is integrated to enable mutual correction and compensation of ammonia nitrogen values, realizing simultaneous measurement of three key parameters: NH₄⁺-N, pH, and temperature .
Compared with traditional Nessler's colorimetric and salicylate method analyzers, the SLDW1110 offers two critical advantages: faster measurement speed (no time-consuming color reactions) and zero waste liquid pollution-making it far more suitable for real-time water environment monitoring and early warning .
