Testing principle of ammonia nitrogen detector
The online ammonia nitrogen testing adopts the principle of ammonia sensing electrode sensing. 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.

2、 If only a single parameter ammonia nitrogen needs to be tested, the optional host Trescon Uno single module online nitrogen and phosphorus analyzer
Namely: Trescon Uno A111 ammonia nitrogen detector=Trescon Uno (host)+ammonia nitrogen analysis module OA110 (module)

The Trescon Uno A111 ammonia nitrogen detector is designed specifically for controlling and monitoring wastewater in water quality monitoring systems and sewage treatment plants. It is a compact and cost-effective ammonia nitrogen detector

Online analysis - Reliable, compact, economical - Ammonia nitrogen detector

3、 If multiple parameters are measured, such as ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, phosphate, total phosphorus, and total nitrogen, the host Trescon online multi parameter nitrogen and phosphorus analyzer should be selected
The Trescon ammonia nitrogen detector is suitable for applications that require accurate testing and real-time adjustment of water treatment processes. Trescon has the characteristics of more accurate and stable testing, and stronger anti-interference. The Trescon ammonia nitrogen detector adopts a modular design, allowing up to 3 modules to be combined freely. The multi parameter monitoring system has unparalleled cost advantages.
