PINH3-900 Ammonia Nitrogen Sensor Online Analyzer for Sewage Water

The ammonia nitrogen concentration was measured by an ion selective electrode method. The ammonia nitrogen sensor is composed of an ammonium ion selective electrode, a potassium ion (optional), a pH electrode and a temperature electrode to form an integrated sensor.
Quantity:
  • PINH3-900
  • PROBEST
  • 90268090

Measurement Principle
The ammonia nitrogen concentration was measured by an ion selective electrode method. The ammonia nitrogen sensor is composed of an ammonium ion selective electrode, a potassium ion (optional), a pH electrode and a temperature electrode to form an integrated sensor. These
parameters can mutually correct and compensate the measurement
value of ammonia nitrogen, and at the same time realize multi-
parameter measurement.

 Features
 sensor can dynamically compensate temperature and pH in

samples
 Digital sensor, strong anti-interference ability, long

transmission distance
 Standard digital signal output for integration and networking

with other devices without a transmitter
 The sensor is easy to install on site, enabling plug and play
 The sensor power supply is reversed and protected. The sensor

RS485 A/B terminal is connected to the power supply protection. Optional time display, data storage and historical data viewing
 Optional data wireless transmission module

 Applications
 Sewage treatment plants monitoring instruments and ammonia nitrogen values in aeration tanks monitoring

instruments
 industrial processes and river water monitoring instruments .
