Reagent-free ion selective electrode nitrate sensor with automatic
temperature and pH compensation, waterproof to IP68
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, support MODBUS
More economical and environmentally friendly, can be monitored
online in real time
Automatically compensate temperature in water
High precision and high stability.

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.
