online ammonia nitrogen sensor PH and Temperature Compensation Technology and its Application in Multi-Scenario Water Quality Monitoring

The online ammonia nitrogen sensor is a device for real-time monitoring of ammonia nitrogen concentration in water, with a measurement range of 0-1000 mg/L. It utilizes a built-in pH electrode and temperature probe for dual compensation, improving measurement accuracy. It is suitable for various water environment monitoring scenarios, including surface water, wastewater, pipeline outlets, and industrial parks.

Ammonia nitrogen is a key indicator in water quality monitoring. Excessive concentrations can seriously harm aquatic ecosystems and affect drinking water safety. Traditional ammonia nitrogen measurement methods are often cumbersome and cannot achieve real-time continuous monitoring. The application of the modern online ammonia nitrogen sensor provides an efficient technical means for online monitoring and rapid response of ammonia nitrogen content in water.

The online ammonia nitrogen sensor can monitor ammonia nitrogen concentration in water bodies in real time, with a typical range of 0 to 1000.00 mg/L, covering the monitoring needs of various water bodies, from clean surface water to high-concentration industrial wastewater. Its core advantage lies in solving a key interference factor in ammonia nitrogen measurement: ammonia nitrogen in water exists mainly in two forms: free ammonia and ammonium ions. The ratio of these two forms changes dynamically with water quality conditions, directly affecting the measurement results.

Specifically, this ratio is highly dependent on the pH value (acidity/alkalinity) and temperature of the water sample. At the same temperature, the higher the pH value, the greater the proportion of free ammonia; and under the same pH conditions, temperature changes also affect the equilibrium state of both. Without correction for these factors, the measurement data will exhibit significant deviations.

Therefore, the advanced online ammonia nitrogen sensor integrates a pH electrode and a temperature sensor to achieve automatic compensation. The sensor simultaneously measures the current pH and temperature of the water body while measuring the ammonia nitrogen concentration. The built-in intelligent algorithm, based on a known chemical equilibrium model, automatically corrects and compensates for the ammonia nitrogen readings based on the real-time measured pH and temperature values, ultimately outputting a corrected value that more accurately represents the total ammonia nitrogen concentration. This dual compensation mechanism greatly improves the reliability and effectiveness of the monitoring data.

With its stable and reliable performance, online ammonia nitrogen sensor is widely used in various complex water environment monitoring scenarios. It can be used for long-term ecological monitoring of natural surface water such as rivers, reservoirs, and lakes, and is also suitable for monitoring pollution sources such as urban sewage pipe networks and industrial wastewater discharge outlets. It also plays an important role in process control at waterworks, water quality management in industrial parks, and aquaculture. By deploying such sensors at different nodes, a real-time, continuous ammonia nitrogen monitoring network can be built, providing timely and accurate data support for environmental protection, production management, and public drinking water safety.
