Product Overview
The SX-CNLNA Series online ammonia-nitrogen sensor requires no reagents and generates no chemical waste, enabling real-time online monitoring. It is equipped with an ammonium-ion electrode, pH electrode, and reference electrode as standard, with an optional potassium-ion electrode. Automatic pH and temperature compensation helps improve measurement accuracy. The sensor supports direct immersion installation and provides a cost-effective solution for online ammonia-nitrogen monitoring. RS-485 output with Modbus protocol enables convenient system integration.
