SUP-DO700 optical dissolved oxygen sensor uses the 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 for the fluorescent substance to return to the ground state. The method is adopted to measure dissolved oxygen, and the measurement does not produce oxygen consumption, the data is stable, the performance is reliable, there is no interference, and the installation and calibration are simple.

The SUP-DO700 controller is used to display the data measured by the sensor. Users can configure and calibrate through the interface of the controller to achieve 4-20mA analog output. Functions such as relay control and digital communication can be realized. This product is widely used in dissolved oxygen monitoring in sewage plants, water plants, water stations, surface water, aquaculture, industry, and other fields.
