Product Description
Product Overview
This IP66-rated ammonia nitrogen transmitter utilizes ion-selective electrode technology to measure NH4-N concentration in water environments. The integrated sensor system combines ammonium ion selective electrode, pH electrode, and temperature electrode for accurate multi-parameter measurement with mutual correction capabilities.
Measurement Technology
The system employs ion-selective electrode methodology to directly detect ammonium ions in water, determining ammonia nitrogen concentration. A pH reference electrode ensures superior stability, while optional potassium ion compensation addresses interference in high-potassium environments.
