Ip68 4~20mA RS485 Ammonia Nitrogen Sensor For Water Quality

Kacise KAN601 Online Ammonia Nitrogen Sensor Patented Probe IP68 Protection Level Easy To Install: 3/4 NPT Thread
 
KAN601 Online Ammonia Nitrogen Sensor
 

Application Environment

KAN601 integrated online ammonia nitrogen sensor is fabricated using a PVC membrane-based ammonium ion-selective electrode for testing ammonium ion content in water with temperature compensation to ensure fast, simple, accurate, and economical testing. The technical parameters, maintenance, and communication protocols of the ammonia nitrogen sensor are described in detail in this user manual.

• Signal output: RS-485 bus, Modbus/RTU protocol, convenient to connect to PLC, DCS, industrial control computer, general controller, paperless recording instrument or touch screen, and other third-party equipment.
• In the patented ammonium ion probe, the internal reference solution oozes extremely slowly from the microporous salt bridge at a pressure of at least 100 KPa (1 Bar). Such a reference system is very stable and has a longer electrode life than conventional industrial electrodes.
• Easy to install: 3/4 NPT thread (pipe thread) for easy submersible installation or installation in pipes and tanks.
• IP68 protection level.

Ammonia gas sensing electrode method:

The ammonia gas sensor is a composite electrode, with a pH glass electrode as an indicator electrode and a silver-silver chloride electrode as a reference electrode. This electrode pair is placed in a plastic sleeve filled with 0.1mol/L ammonium chloride inner liquid. The end of the tube is fitted with a hydrophobic semi-permeable membrane close to the sensitive membrane of the indicator electrode to separate the inner electrolyte from the outer test solution. Semi-permeable membrane, there is a very thin membrane between the pH glass electrode. When a strong alkali solution is added to the water sample to increase the pH to above 11, the ammonium salt is converted into ammonia. The generated ammonia passes through the semi-permeable membrane due to diffusion (water and other ions cannot pass through), making the ammonium chloride electrolyte membrane layer NH3+H2O=NH4++OH- The reaction moves to the right, causing the hydroxide ion concentration to change. The change is measured by a pH glass electrode. The electromotive force measured under a constant ionic strength is the logarithm of the ammonia nitrogen concentration in the water sample.
