Ammonia Nitrogen NH3-N Analyser

Online Effluent Monitoring System

The AN-ISE sc Combination Sensor from Hach enables continuous, reagent-free, direct measurement of both ammonium (NH₄⁺) and nitrate (NO₃⁻) using ion-selective electrode (ISE) technology. It eliminates the need for reagents or sample preparation, saving time and reducing operational costs. With built-in automatic compensation for potassium (K⁺) and chloride (Cl⁻) interferences, the AN-ISE sc delivers accurate results in real-time for reliable process control. Its modular Cartrical plus sensor design simplifies maintenance by integrating five electrodes into a single replaceable cartridge. Fully compatible with Hach SC controllers and the Claros Water Intelligence System, this sensor helps optimize efficiency, reduce downtime, and enhance operational confidence.
