online ammonia nitrogen sensor

1. Online ammonia nitrogen sensor application environment

online ammonia nitrogen sensor uses the electrode method to measure ammonia nitrogen with temperature compensation to ensure fast, simple, accurate and economical measurement.It is used for ammonia nitrogen concentration in environmental water quality and can meet the measurement requirements of ammonia nitrogen in most industrial environment applications.

2. Product features of online ammonia nitrogen sensor

The built-in pH electrode can detect the pH of water quality and compensate ammonia nitrogen in real time according to the pH concentration.

Signal output: RS485 (MODBUS)

The electrode is a composite electrode, consisting of a working electrode and a reference electrode made of polyvinyl chloride and ionic active materials.

Internal signal isolation technology, strong anti-interference.

It has the characteristics of fast, accurate measurement and easy operation.

4. Maintenance and maintenance of online ammonia nitrogen sensor

Before testing, remove the protective covers of the ammonium ion measurement electrode and pH electrode. The electrodes should be soaked in clean water for 2 hours. After activation is completed, clean them in deionized water before testing. If the electrode is not used for a long time (more than two weeks), it should be stored dry, and the sensing element of the electrode should be put into a protective cap. In order to obtain high-precision results, it is recommended to repeat these steps: remove the electrode from the standard solution, clean it, blot it dry, and then immerse it in the standard solution (soak for at least 2 minutes to obtain a stable reading) to ensure that the electrode is properly rinsed and preprocessing.

Check whether the terminal block is dry. If there is any stain, please wipe it with absolute alcohol and blow dry before use. Long-term immersion in distilled water or protein solutions should be avoided, and contact with silicone grease should be avoided. If the electrode has been used for a long time, its PVC membrane may become translucent or have sediments attached. In this case, it can be rinsed with distilled water (or deionized water). When the electrode is used for a long time and measurement errors occur, correction must be performed.
