Product Details

1NHN-406-A online ammonia nitrogen sensorApplication Environment Description

The NHN-406A integrated online ammonium nitrogen sensor is made of an ammonium ion selective electrode based on PVC film, which is used to test the ammonium ion content in water. It has temperature compensation to ensure fast, simple, accurate, and economical testing. This user manual provides a detailed introduction to the technical parameters, usage, maintenance, and communication protocol of ammonium nitrogen sensors.

Signal output: RS-485 bus, Modbus/RTU protocol, convenient for connecting to third-party devices such as PLCs, DCS, industrial control computers, general-purpose controllers, paperless recording instruments, or touch screens.

The ammonium ion electrode has an internal reference solution that slowly seeps out from the microporous salt bridge under a pressure of at least 100KPa (1Bar). This reference system is very stable, and the electrode life is longer than that of ordinary industrial electrodes.

Easy to install: 3/4NPT pipe thread, easy to sink or install inside the tank.

IP68 protection level.
