DO Fluorescent Dissolved Oxygen Sensor

The DO fluorescent dissolved oxygen sensor uses the "dynamic fluorescence quenching" principle to measure dissolution in water. The film on the top of the sensor is covered with a layer of fluorescent material. When the blue light emitted by the light emitting diode (LED) is irradiated on the fluorescent material, the fluorescent material will emit fluorescence when it returns from the stress state to the ground state, and the fluorescence is the test signal. The higher the concentration of dissolved oxygen, the shorter the duration of fluorescence, and the concentration of dissolved oxygen can be measured by measuring the duration of fluorescence. Built-in temperature, pressure, automatic compensation of dissolved oxygen value.
