The fluorescence dissolved oxygen meter is based on the principle of fluorescence quenching. As shown in the figure: blue Light irradiation to the fluorescent material stimulates the fluorescent material and emits red light due to the oxygen fraction Son can take away energy (quenching effect), so the time and strength of the red lightDegree is inversely proportional to the concentration of the oxygen molecules. By measuring the phase of the excited red light with the reference light Position difference, and compared with the internal calibration values, so that the concentration of oxygen molecules can be calculated.
1. Innovative principle of fluorescence method, no need to replace the diaphragm and electrolyte, basic maintenance free;
2. No oxygen consumption, no flow rate and agitation requirements, not subject to the intersection of the following substances
Interference: H2S, pH, Co2 +, NH4 +, SO4 2-, Cl-, Cl 2, etc.;
3. Digital sensor, with strong anti-interference ability and stability, sensor electricity The cable length can be hundreds of meters;
4. Sensor plug and play, automatic recognition, support dual-channel input;
5. The instrument can provide isolated RS232 digital interface and isolated RS485 digital interface,
6. Support the standard Modbus ASCII and Modbus RTU protocol;
7. Support for Both Chinese and English languages;
8. Relay output programmable: any relay can be set to high alarm, low alarm,timer mode;
9. It has the function of automatic preservation of historical data, which can store and query 10 years of historical data
