The dissolved oxygen sensor uses the fluorescence method to measure the dissolved oxygen. The emitted blue light shines on the fluorescent layer, and the fluorescent substance is excited to emit red light, and the oxygen concentration is inversely proportional to the time for the fluorescent substance to return to the ground state. By using this method to measure the dissolved oxygen, there is no oxygen consumption during the measurement, the data is stable, the performance is reliable, there is no interference, and the installation and calibration are simple. This product is widely used in the...
