Online ISE Method RS485 Ammonia Nitrogen Sensor For Sewage Treatment Plant


Ion-selective ammonia nitrogen (NH4-N sensor is a specific type of ammonia nitrogen sensor, which is based on ion-selective electrode technology and is used to detect the concentration of ammonia nitrogen in water.


High selectivity: The ion-selective method sensor uses a specific ion-selective electrode, which has high selectivity and can specifically respond to ammonia nitrogen ions.
High Sensitivity: This sensor can detect low concentration of ammonia nitrogen with high sensitivity.
Real-time monitoring: It can monitor the concentration of ammonia nitrogen in the water body in real time and provide accurate real-time data.
Automation integration: The ion-selective ammonia nitrogen sensor can be integrated with automation systems for remote monitoring and data logging.
Fast response: This kind of sensor usually has a fast response time and can quickly respond to changes in the concentration of ammonia nitrogen in water.
High precision: Ammonia nitrogen sensors usually have high measurement precision and can provide accurate data.
Ease of Installation and Maintenance: Most ammonia sensors have simple installation steps and generally require less maintenance.

Application Environment:
Water quality monitoring: Ion selection method ammonia nitrogen sensors are widely used in natural water bodies, water treatment plants, sewage treatment plants, etc., to monitor the concentration of ammonia nitrogen in water bodies to maintain the health and compliance requirements of water bodies.

Agricultural management: In the field of agriculture, the ion-selective ammonia nitrogen sensor can be used to monitor the ammonia nitrogen content in water

Industrial application: In the process of industrial wastewater treatment, these sensors are used to monitor the ammonia nitrogen content in the wastewater to ensure that the discharge meets environmental protection standards.

Environmental monitoring: Ammonia nitrogen sensors are widely used in environmental monitoring, especially water quality monitoring, which helps to protect the water environment.

Water treatment: Ammonia sensors can be used in sewage treatment plants to monitor the ammonia nitrogen in the influent and effluent to ensure the effectiveness of the treatment process.

Research and Education: Ammonia sensors are also used in scientific research and educational experiments to study and understand the behavior of ammonia in water.

Natural water bodies: Including rivers, lakes, oceans and other natural water bodies, used to monitor water quality conditions.

Sewage treatment plant: It is used to monitor the ammonia nitrogen content in the water body before and after treatment to ensure that the discharge of wastewater meets the standards.


In general, ammonia nitrogen sensors play an important role in the fields of water environment monitoring and protection, agricultural management, industrial control, etc., and contribute to the realization of environmental sustainable development and resource protection.
