WCD3412 optical dissolved oxygen sensors use the principle of "dynamic fluorescence quenching" to measure dissolution in water. When the blue light emitted by the light-emitting diode (LED) hits the fluorescent material, the fluorescent material emits 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, and automatic compensation of dissolved oxygen values.
