PINH3-900 Ammonia Nitrogen sensor Online Analyzer

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 .
