KFDO500 compact dissolved oxygen meter water quality for aquaculture PVC material sensor
Product Introduction
Fluorescence dissolved oxygen meter KFDO500 is based on the quenching principle of active fluorescence by specific substances in physics.
The modulated green light hits the fluorescent material for a period of time to excite and emit red light. Because oxygen molecules can take away energy (quenching effect),
Therefore, the time and intensity of red light is inversely proportional to the concentration of oxygen molecules.
We used a red light source synchronized with the green light as a reference,
Measure the direct phase difference between the excited red light and the reference light, and compare it with the internal calibration value,
So as to calculate the concentration of oxygen molecules, and output the final value after temperature compensation.
Performance characteristics:
1. Principle of fluorescence quenching, no electrolyte digestion, maintenance-free
2. No oxygen consumption, no flow rate and agitation requirements
3. No interference from chemicals such as sulfides
4. High resolution and measurement accuracy
5. Chinese menu operation is simple, easy to operate and master
6. Special thickened cap film, not easy to wear, longer service life
7. The unique protective cover design prevents irreversible damage caused by the cap film hitting hard objects during the sensor reuse process
