China Probest Online Spectrometer Ammonia Nitrogen Electrode Nh4 Sensor Analyzer
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 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.
