The dissolved oxygen sensor of JY-DO700 uses fluorescence method to measure dissolved oxygen. The emitted blue light shines on the fluorescent screen, 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. The dissolved oxygen measured by this method does not generate oxygen consumption during measurement, with stable data, reliable performance, no interference, and simple installation and calibration.

This product is widely used for dissolved oxygen monitoring in sewage treatment plants, waterworks, water stations, surface water, aquaculture, industry and other fields. The configured waterproof high-performance controller can anthropomorphize the data measured by the sensor. Users can also achieve 4-20mA analog output through the interface configuration and calibration of the controller. Implement relay control and digital communication functions.

1. No need to replace solid-state electrodes or electrolytes

2. No flow rate or stirring interference requirements

3. Higher resolution and measurement accuracy

4. Stable measurement without drift phenomenon

5. Immune sulfide, will not cause "poisoning" phenomenon due to sulfide products

6. The sensor has a lifespan of up to 5 years

7. Not affected by "thermal disturbance"

8. Not subject to cross interference from substances such as H2S, pH, CO2, NH3, SO4, CL -, etc

9. The advantage of small volume is more obvious

10. Ready to install and use, no calibration required
