Product details
| Fluorescence method for measuring dissolved oxygen analyzerDetailed Introduction |
DO-702 Using fluorescence method to measure dissolved oxygen, the emitted blue light is irradiated on the fluorescent layer, and the fluorescent substance is excited to emit red light. The oxygen concentration is inversely proportional to the time it takes for the fluorescent substance to return to the ground state. 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. Humanized sensing of dissolved oxygen data measured by sensors.
