Maintenance Methods and FAQ
Maintenance Schedule and Method
1. Maintenance Schedule
It is recommended to periodically calibrate or clean the sensor surface according to the actual application scenario.
2. Maintenance Methods
Sensor maintenance
1) Sensor outer surface: Clean the outer surface of the sensor with tap water. If there is still debris, wipe it with a soft, damp cloth.
2) Check the cable of the sensor: the cable should not be tightened during normal operation, otherwise the cable inside the cable will be broken, causing the sensor to not work properly.
3) Sensor storage: When the sensor is not in use, the black plastic cap should be fastened to 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 placed with potassium chloride. Preserved in the solution.
The Matters Needing Attention
The probe contains sensitive optical and electronic components. Make sure the probe is not subject to severe mechanical shock. Damage to the sensor due to impact or man-made will not be covered by the warranty. The sensor inlet water is not covered by the replacement of the pH electrode.

Procedure to get NH3_N value
Figure 91:Flow chart to get NH3_N measurement
Start brush active – make the brush active once power on , then the brush will work at the set interval time.
Get temperature and NH3_N values – Get measurement results including temperature (C) and NH3_N (mg/L) after 20 seconds of brush active.
(mg/L) after 20 seconds of brush active.
Note: Please pay attention to highlighted portion (red) in the flow chart above. It’s highly recommended that customers get an average NH3_N results after 10 consecutive measurements, then perform display or other process.
