Product Description:

The fluorescence dissolved oxygen electrode is based on the principle of quenching active fluorescence by specific substances in physics. From a light emitting diode ( LED） The emitted blue light irradiates on the fluorescent substance on the inner surface of the fluorescent cap. The fluorescent substance on the inner surface is excited and emits red light. By detecting the phase difference between the red light and the blue light, and comparing it with the internal calibration value, the concentration of oxygen molecules is calculated, and the final value is automatically compensated for by temperature and air pressure.

Provided by Thunder Magnetic DO-960 Fluorescence dissolved oxygen electrode, which is developed using advanced fluorescence technology, fully meets the standard requirements and has the following advantages:
● No polarization required: polarographic dissolved oxygen electrodes generally require polarization, while fluorescent electrodes do not require polarization, which greatly improves the experimental efficiency.
● No frequent calibration required: Fluorescent dissolved oxygen electrodes have been calibrated before leaving the factory.
● No film configuration required: No film required for fluorescent dissolved oxygen electrode, the electrode is simple to operate and has low maintenance.
● No need to fill the electrolyte: Since the fluorescent electrode does not need to be equipped with a thin film, the fluorescent oxygen electrode is directly measured by the principle of fluorescent quenching, so the fluorescent dissolved oxygen electrode does not need to fill the electrolyte between the anode and the cathode according to the operation steps of the polarographic dissolved oxygen electrode, and perform the electrolyte through the electrode-on-electrode polarization process. This not only saves time costs, but also reduces maintenance costs.
● No oxygen consumption: Fluorescent dissolved oxygen electrode adopts physical and optical principles, and is not affected by chemical substances such as sulfides, chlorides and common metal ions in the water quality during the measurement process.
● Not limited by flow rate and stirring requirements: Since the entire measurement process does not consume oxygen, there is no need to replenish oxygen through stirring.
● Durable fluorescent cap: The fluorescent cap has a long service life and is easy to clean. If the fluorescent cap is partially contaminated, it can still maintain its accuracy after washing.
