4. Installation Notes
The chlorophyll sensor is designed for submerged installation in water quality monitoring applications. During installation, keep the sensor at least 3 cm away from side walls and at least 10 cm away from the bottom to reduce measurement interference and prevent sediment or wall reflection from affecting the optical measurement window.
For long-term use in water, seawater, or humid outdoor environments, all wiring joints should be waterproofed, and the user-side cable should have corrosion-resistant protection. Before power-on, check the wiring order carefully to avoid damage caused by incorrect wiring.
During calibration, place the sensor vertically in distilled water or standard solution and keep the sensor front end at least 10 cm away from the bottom of the beaker. Wait 3 to 5 minutes until the readings stabilize before calibration.
5. Maintenance Notes
The cleanliness of the measurement window is important for accurate readings. Clean the external sensor surface with tap water. If debris remains, wipe it gently with a wet soft cloth. For stubborn dirt, a small amount of household detergent can be added to tap water.
Check the cable regularly and ensure it is not under tension during operation, because excessive pulling may damage internal wires and cause sensor malfunction. Inspect the measurement window for dirt during routine maintenance. The sensor contains sensitive optical and electronic components and should not be exposed to strong mechanical impact.
