Digital Fluorescent Dissolved Oxygen Sensor BH-DY12

The BH-DY12 Fluorescent Dissolved Oxygen Sensor uses fluorescence quenching detection technology to convert the optical signal of the interaction between oxygen molecules and fluorescent molecules into
electrical signals. Through 3D algorithms, stable and sensitive oxygen concentration or oxygen partial pressure changes are obtained. Compared with the second generation electrochemical measurement
technology, the LH-DY12 fluorescent dissolved oxygen sensor measures higher, is plug-and-play and does not require the addition of any chemical reagents. It is an ideal choice for industries such as chemical industry, biomedicine, nuclear power, sewage and wastewater treatment, and smart aquaculture. Ideal for water quality testing.
