This sensor is coated with a luminescent material. Green light from an LED is transmitted to the sensor surface. The green light excites the luminescent material. As the material relaxes it emits red light. The time it takes for the red light to be emitted is measured. Between the flashes of blue light, a red LED is flashed on the sensor and used as an internal reference. Increased oxygen in the sample decreases the time it takes for the red light to be emitted. The time measurements correlate to the oxygen concentration. online industrial DO electrode
The instrument is manufactured in strict accordance with the requirements of the ISO9001 2015 quality management system and is subject to strict testing and correction before delivery, and meets the requirements of the specification

Installation diagram
1. Sensors stainless steel surface dirt can be wiped with a soft cloth.
2. Wipe the dirt on the outer surface of the fluorescent cap with a wet soft cloth after cleaning it with water. Do not force
3. Check if the fluorescent cap is damaged when the data measurement deviation is large
4. When the sensor is in use, it is necessary to ensure that more than 1/3 of the water is immersed in the water sample to
5. Avoid the force of the sensor itself with the wire
6. The outer surface of the fluorescent cap should be protected from contact with hands and hard objects to avoid scratching.
7. Non-contact organic solvents such as alcohol on the outer surface of the fluorescent cap
8. The fluorescent cap needs to be covered with a dust-proof cap when the fluorescent cap is not in use, the sponge inside the dust-proof cap is kept wet. Measuring Range 0-20.00mg/L or 0-200%saturation level
