Quantity:
  • PINH3-900

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  the measurement value of ammonia nitrogen, and at the same time realize multi-parameter measurement.

Features

² Standard digital signal output for integration and networking with other devices without a transmitter.

² The sensor is easy to install on site, enabling plug and play.

² The sensor power supply is reversed and protected. The sensor RS485 A/B terminal is connected to the power supply protection.

²
Optional data wireless transmission module.

Applications

² Sewage treatment plants monitoring instruments and ammonia nitrogen values in aeration tanks monitoring instruments

²
Industrial processes and river water monitoring instruments.
