Measuring principle:
1. The sensor surface containing a fluorescent dye or substance;
2. LED emits blue light strikes the sensor surface;
3. To make the blue fluorescent substance excited, and emit red light;
4. emitting red light time measurement by the optical sensor;
5. The red LED light is used to make reference phase contrast;
6. The more oxygen present in the sample, it will result in a reduction of red light emission time of the red light emission time is determined by measuring the optical sensor and the oxygen concentration in the relevant decisions;
7. ASI proprietary algorithm than the usual linear algorithm to improve accuracy.
Characteristics:
1. The price is reasonable, the complete system;
2. maintenance-free;
3. No electrolyte solution was added;
4. No anode, cathode cleaning or replacement;
5. In most applications of at least one year, without calibration or replacing the sensor cap;
6. No measurement drift;
7. No need to maintain the flow of the sample to ensure accuracy;
8. Functional comprehensive and immediately available.
