Online Ammonia Nitrogen Sensor RS485 Modbus PLC DCS
1.Application Environment
Kacise introduces an online ammonia nitrogen sensor that requires no reagents, is green and non-polluting, and can be monitored online in real time. Integrated ammonium, potassium (optional), pH and reference electrodes automatically compensate for potassium (optional), pH and temperature in water. It can be directly put into installation, which is more economical, environmentally friendly and convenient than traditional ammonia nitrogen analyzer. The sensor adopts RS485 output and supports Modbus for easy integration.

Tip: Discussion for Ammonia Nitrogen in Aquaculture Water
To sum up, ammonia nitrogen pollution has become the main stress factor restricting the aquaculture environment. The ammonia nitrogen pollution produced in aquaculture has been listed as one of the pollutants for mandatory emission reduction in environmental protection and has been researched by environmental protection workers and technology. The extensive attention and research of the authors, the determination of ammonia nitrogen in the aquaculture water body, helps to evaluate the pollution and "self-purification" of the water body. Several existing detection methods have certain defects. For example, the Nadler reagent spectrophotometry has high requirements for the preparation of chromogenic reagents. The amount of HgCI2 added determines the number of chromogenic groups obtained, which in turn affects the sensitivity of the method. However, the method does not give the exact dosage, and it needs to be judged based on the phenomenon in the reagent preparation process, which is highly empirical and therefore difficult to grasp. Due to the narrow oxidation range of gas-phase molecular absorption spectrometry, the use of a direct measurement standard curve will cause large errors. The aquaculture water contains a large amount of nitrate nitrogen, which will cause strong interference in the determination of ammonia nitrogen and affect the measurement results. The hypobromite oxidation method has a large error when it is used to determine the aquaculture water containing more organic matter, and the blank value of the aquaculture water sample is high, which will cause serious interference. All these problems require us to further study and improve, to improve the detection method of ammonia nitrogen in aquaculture water samples, to accurately grasp the change of ammonia nitrogen in aquaculture water samples, to reduce the harm of ammonia nitrogen to aquatic organisms and to protect human health.
