    Frequently Asked Questions
    Q
    What measurement method does the Chlorophyll Sensor use?
    The chlorophyll sensor uses the fluorescence method. It emits a specific wavelength of light to excite chlorophyll molecules in the water, and then measures the fluorescence signal emitted, which is directly proportional to the chlorophyll-a concentration.
    Q
    What is the measurement range and accuracy of the chlorophyll sensor?
    The sensor measures chlorophyll concentrations from 0 to 500 ug/L with an accuracy of ±3% F.S. It also measures water temperature in the range of 0–50℃ with an accuracy of ±0.5℃.
    Q
    Does the chlorophyll sensor require chemical reagents for operation?
    No. The sensor is completely reagent-free. It operates using optical fluorescence technology, which eliminates the need for chemical reagents, reducing costs and environmental impact significantly.
    Q
    How does the self-cleaning system work, and why is it important?
    The sensor is equipped with an automatic wiper mechanism that regularly cleans the optical window to prevent biofouling and sediment buildup. This ensures long-term measurement stability and reduces the frequency of manual maintenance, especially in environments with high biological activity.
    Q
    What communication protocol does the sensor support, and how can it be integrated into a monitoring system?
    The sensor supports RS-485 output with MODBUS protocol, making it compatible with most industrial data loggers, PLCs, and SCADA systems. It operates on 9–24 VDC power supply and can be easily integrated into existing water quality monitoring networks.
