RS485 Nitrate ion selective electrode NO3 ion sensor nitrate sensor
electrode Ion Selective Eectrode Method
Overview
Online nitrate sensor requires no reagents, is environmentally
friendly and pollution-free, and can be monitored online in real
time.
Integrate nitrate ion, sodium ion (optional), and reference
electrode,
automatically compensate temperature in the water. It can
be directly put into installation, which is more economical,
environmentally
friendly, convenient and quicker than traditional nitrate
analyzers. The
sensor has excellent reliability, adopts RS485 output, supports
Modbus,
and is easy to integrate.
Features
- Digital sensor, RS-485 output, supports MODBUS
- No reagents, no pollution, more economical and environmentally
friendly
- Automatically compensate pH and temperature in water
- With self-cleaning brush to prevent microbial attachment and longer
maintenance intervals

Maintenance method
Sensor maintenance
1) External surface of the sensor: Wash the external surface of the sensor with tap water. If debris
remains, wipe it with a moist soft cloth.
2) Check the cable of the sensor: The cable should not be tight during normal work, otherwise the
internal wires of the cable will be easily broken and the sensor
will not work properly.
3) Sensor storage: When the sensor is not in use, you should fasten the black plastic
cap and check whether the sponge inside is wet. If it is not wet
enough, please add 3mol / L potassium chloride solution and let the
electrode be stored in the solution with potassium chloride.
