| CS4760D Fluorescence Dissolved Oxygen 【Download】 The dissolved oxygen sensor uses fluorescence method to measure dissolved oxygen. The blue light emitted shines on the fluorescent layer, and the fluorescent material is excited to emit red light. The oxygen concentration is inversely proportional to the time when the fluorescent material returns to the ground state . When this method is used to measure dissolved oxygen, there is no oxygen consumption during measurement, the data is stable, the performance is reliable, there is no interference, and the installation and calibration are simple. The product is widely used for dissolved oxygen monitoring in sewage plants, waterworks, water stations, surface water, aquaculture, industry and other fields. |

| CS4750D Fluorescence Dissolved Oxygen 【Download】 The dissolved oxygen sensor uses the fluorescence method to measure the dissolved oxygen, and the blue light emitted shines on the fluorescent layer. When excited, the substance emits red light, and the oxygen concentration is inversely proportional to the time when the fluorescent substance returns to the ground state. This method can measure dissolved oxygen without oxygen consumption, with stable data, reliable performance, no interference, and simple installation and calibration. |
