1、 Module introduction: ammonia nitrogen analysis module OA110Ammonia nitrogen online monitoring device, continuous testing, automatic calibration, fast response

Feature: Linear testing range: 0.00... 10.00 mg/l NH4-N 10.0... 100.0 mg/l NH4-N 100... 1000 mg/l NH4-N Three level automatic range switching adopts a quartz controlled pump to ensure excellent long-term stability and continuous operation. The reaction time is less than 3 minutes. When testing the outlet water flow containing a small amount of suspended particles, no filtration is required

Testing principleThe ammonia nitrogen online monitoring instrument adopts the sensing principle of ammonia sensing electrode. Add NaOH solution to the sample, mix thoroughly, and adjust the pH value of the sample to>12. At this point, all ammonium ions are converted into gaseous NH3. In addition, add chelating agents such as EDTA to adjust the sample and prevent the formation of calcium salt precipitation. The free ammonia gas passes through a semi permeable membrane (made of Teflon) and enters the interior of the ammonia sensing electrode to participate in chemical reactions, changing the pH value of the electrolyte inside the electrode. The change in pH value is linearly related to the concentration of NH3, which is sensed by the electrode and converted into the concentration of NH4-N by the host.
