Water Quality Sensor No Film Not Affected by Surfactants No
Micropores NO2 - Nitrite sensor RS485 Modbus Output
1. Introduction
The reference electrode silver/silver chloride electrode is
encapsulated in a closed electrolyte cavity, and the working
electrode gold electrode is directly placed. Test solution contact,
reference electrode through the ionic membrane and the external
solution to complete the charge exchange NO2- in solution. Directly on the surface of the working electrode is
oxidized to form a current, the current size and solution of NO2- proportional to content.
2. Features
- no pharmacy
- No film, not affected by surfactants.
- No micropores, there is no danger of holes blocking in the sewage.
- RS485 digital output.
- Easy maintenance, no need to replace the diaphragm.
- Automatic temperature compensation
- No pressure balance required

6. Maintenance
Zero calibration:
This electrode has different zero points for different water
bodies, so it is necessary to mark the zero point.
Calibrate the electrode with a standard solution:
At different concentrations of NO2- , from the lean to the rich, test the potential of the electrode.
Record the value of mA and NO2- , draw electrode"mA--NO2- "
Standard curve. Do not need to draw a standard curve if using ion
meters. Operate accordingly to the user manual.
NO2- Standard solution, please see: GB5750.5.10-2006;
- Working electrode surface maintenance: brush the working electrode
surface with a small brush every month.
- Electrolyte replacement: Replace the electrolyte once a year.
