- APPLICATION
- Suitable for mining industry applications as well as water and sewage treatment. It is reliably monitored:
- Flotation process
- Washing and immersion process
- Neutralization process
- Intake and outlet
- FUNCTIONAL CHARACTERISTICS
- Fluorescence dissolved oxygen instrument (hereinafter referred to as the instrument) is a water quality online monitoring instrument with a microprocessor. Widely used in industrial water
- domestic water and sewage treatmentand aquaculture. The oxygen content in the aqueous s
- olution was continuously monitored and controlled. The instrument adopts LCD LCD screen; intelligent Chinese menu operation; with current or voltage output
- free setting of satellite measurement range
- alarm warning and two sets of relay control switches and adjustable lag range; automatic or manual temperature compensation
- and automatic electrode calibration.
DESCRIBE
1.Structural features The whole measurement system is mainly composed of two parts: instrument (secondary table) and dissolved oxygen electrode (primary table). The dissolved oxygen electrode contacts the measured solution, and the instrument shows the oxygen content, temperature and working state of the aqueous solution.
2.The fluorescence dissolved oxygen probe consists of three parts: optical path system, fluorescence sensitive film and optical detection system. After the probe is inserted into the medium to be measured, the oxygen in the medium immediately diffuses into the silicone molecular layer and quickly reaches equilibrium. The modulated blue light is hit to the fluorescent layer, and the fluorescent molecules produce red fluorescence. The fluorescent molecules are quenched after encountering oxygen, and the fluorescence intensity and response time change with the oxygen content. Oxygen content was determined by detecting the change in fluorescence response time.
