5.  Installation

Flow cell installation

6. Structure

7. Maintenance

• Calibration:

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.
