Product details

1.Application environment of online ammonia nitrogen sensor

online ammonia nitrogen sensor does not require reagents, online monitoring, direct installation, testing is fast, simple, accurate and economical.Used for ammonia nitrogen concentration in environmental water quality, it 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 and compensate for ammonia nitrogen in real time according to the pH concentration.

Signal output: RS485 (MODBUS)

The electrode is a composite electrode, which is composed of a working electrode and a reference electrode made of polyvinyl chloride and ion active substances.

Internal signal isolation technology, strong anti-interference ability.

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

4. Online ammonia nitrogen sensor maintenance and care

Before testing, remove the protective covers of the ammonium ion measuring electrode and the pH electrode. The electrodes should be soaked in clean water for 2 hours. After activation, they should be cleaned in deionized water and then tested. If the electrodes are not used for a long time (more than two weeks), they should be stored dry, and the sensing elements of the electrodes should be covered with protective caps. In order to obtain high-precision results, it is recommended to repeat these steps: remove the electrodes from the standard solution, wash, dry, and then immerse them in the standard solution (immerse for at least 2 minutes to obtain stable readings) to ensure that the electrodes are properly rinsed and pretreated.

Check whether the terminal is dry. If there is any stain, wipe it with anhydrous alcohol and use it after drying. Avoid long-term immersion in distilled water or protein solution, and prevent contact with silicone grease. The PVC film of the electrode that has been used for a long time may become translucent or have sediment. In this case, it can be rinsed with distilled water (or deionized water). If the electrode has been used for a long time and measurement errors occur, it must be calibrated.
