Industrial Ammonia Nitrogen Sensor Can Be Equipped With A Reference Electrode, PH Electrode, NH4+ Electrode, ORP Or K+ (choose One Of The Two), And The Electrode Is Automatically Temperature-compe
1.Introduction to the New KNF-107A+ Ammonia Nitrogen Sensor
KNF-107A+ Ammonia Nitrogen Sensor Up to four electrochemical electrodes can be installed, namely a reference electrode, a pH measurement electrode, an NH4+ electrode, and an ORP or K+ (choose one) electrode. All electrodes are supported for on-site replacement by users. They can automatically compensate for NH4+, pH and temperature, and calculate the ammonia nitrogen (NH4-N) value.
2.Advantages and Features of the KNF-107A+ New Ammonia Nitrogen Sensor
1. The samples do not require pretreatment and are suitable for continuous online monitoring
2. The NH4+ ion electrode and the polyester liquid contact reference electrode (unconventional porous liquid contact) have a longer service life and less drift.
3. RS485 output, supporting Modbus RTU protocol.
4. Built-in isolator, with better anti-interference ability.
5. Support water leakage alarm.
6. Waterproof rating IP68
Note: Ion electrodes are only suitable for freshwater applications and are not applicable to seawater or Marine aquaculture.
