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.

Brief introduction:
Note: The ion electrode is only suitable for fresh water application scenarios, not for sea water.
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.
