Florescence from a fluorescent material excited by light from a blue light-emitting diode (LED) is quenched by oxygen passed through a DO permeable. By the absorption of blue light, the fluorescent material excited the red light. The emission map is measured by recording the emission spectra resulting from a range of excitation wavelengths and combining them all together. From the variation of wavelength, the concentration of oxygen is calculated by the temperature and barometric pressure compensation.
REX developed DO-960 luminescent Do Electrode which not only adopts advantage technique but also meets the standards. The advantages are followed:
- No polarization: By fluorescence technique adopt, the efficiency of measuring is improved
- Low-frequency calibration: Default calibration is completed.
- No membrane: Low cost for the Electrode maintenance without membrane
- No reference electrolyte: By fluorescence technique, no membrane and electrolyte adopt in the electrode. This improved efficiency and help the maintenance of the electrode.
- No oxygen-consuming: Florescence is a physic process, which doesn’t consume oxygen in sample. The measurement process is stable without the affection of the chemicals.
- Fewer restrictions: No oxygen-consuming result in less restriction, the measurement is not affected by the speed of flow and the stirring speed.
- Durable cover: Polymer material cover, easy to clean and long service life.
