Water Quality Nitrate Nitrogen Sensor


Online Ammonia Nitrogen Sensor

Instrument Introduction


KANN300 Series online Ammonia-nitrogen/nitrate- nitrogen Sensor is an online water quality Sensor developed on the basis of digital water quality analysis platform. Integrated design, using industrial online ion selective electrode, digital, intelligent sensor design concept. The functions of electrode signal detection, temperature detection, automatic compensation and digital signal conversion are realized in the instrument. RS485 signal output, easy networking and system integration, widely used in surface water, pollution sources and other industries.


  • Integrated design, immune to electromagnetic interference
  • Industrial online ion-selective electrode, can work stably for a long time
  • Multi-parameter compensation algorithm of pH, temperature, potassium ion (K +) or chloride ion (Cl -)
  • Built-in Air Purge automatic cleaning system, greatly reducing the maintenance workload
  • Stainless steel case, IP68 waterproof grade, suitable for various working conditions
  • RS485 signal output, Standard Modbus protocol, easy integration, networking
