This LoRaWAN ammonia nitrogen monitor uses spread spectrum technology and has strong remote communication capabilities. Equipped with temperature and pH compensation, accurate measurement, can be directly installed, economical and convenient.

ZW-NHN-PRA is an integrated online ammonia nitrogen sensor based on a PVC membrane ammonium ion-selective electrode. It features real-time temperature compensation for fast, simple, accurate and cost-effective measurement of ammonium ions in water. The sensor supports RS‑485 and Modbus/RTU for easy integration with PLC, DCS, industrial controllers and other third‑party devices. Its patented ion probe with a slow‑leak reference system ensures high stability and extended electrode life. With 3/4 NPT threads and IP68 protection, the sensor enables easy installation in submerged, pipeline or tank environments.
