Integrated pH Electrode ISE Online Ammonia Nitrogen Sensor

Daruifuno online ammonia nitrogen sensor NH351 does not require reagents, is green and pollution-free, and can be monitored online in real time. Ammonia nitrogen electrodes usually consist of three main parts: electrode body, reference electrode and membrane layer. The electrode body is usually made of sliver or sliver/sliver chloride and is connected to cable to transmit the measurement signal to the detection instrument. The reference electrode usually uses a silver/silver chloride electrode, which is used to provide a stable potential and maintain pH stability. The membrane layer is a special material that selectively allows ammonia nitrogen to pass through while preventing other impurities from reacting with the electrode. The ammonia nitrogen sensor is based on the reaction principle of competition between ammonia nitrogen and hydrogen ions in water for free electrons. At a specific pH value, ammonia nitrogen will be replaced by hydrogen ions(H+) in water molecules to form ammon…
