    FAQ

    1. What is the measuring principle of this dissolved oxygen sensor?
    A: This dissolved oxygen sensor uses the fluorescence method, covering the detection head with a layer of fluorescent material, and the LED light source in the sensor emits blue light to the head.The fluorescent substance on the surface emits red light when the fluorescent substance is excited. The higher the dissolved oxygen concentration, the shorter the time from emitting blue light to red light. Use red light release timeThe phototropism between the concentration of dissolved oxygen and the concentration of dissolved oxygen, the sensor calculates the concentration of dissolved oxygen in the medium.
    2. What is the advantage of digital dissolved oxygen sensor?
    A: The digital DO sensor is conducive to long-distance signal transmission without serious signal attenuation. The sensor has RS485 interface, standard Modbus RTU communication protocol.
    3. Can the DO sensor work under water?
    A: Certainly. The protection grade of the dissolved oxygen sensor is IP68, it can work under water for a long time.

    4. How long has the fluorescence technology been in use?

    Fluorescence technology used to detect oxygen uptake in the medical industry for decades.

    In the early 2000s, the technology was adapted for use in measuring dissolved oxygen in biological reactors.

    The key issues in making the technology viable in the water treatment industry were the durability of the sensing element and cost.

    Another important concern was packaging the system in a way that was easy to use and required very little maintenance.


    5. What is the wire length of the DO electrode?
    A:
    The lead wire of this electrode is 1 m by default, other lengths need to be customized, contact our customer service, the price will vary with the change of length.
