PINH3-900 Ammonia Nitrogen Sensor Online Analyzer for Sewage Water
Product Description
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 .
