The LH-DY12 Fluorescent Dissolved Oxygen Sensor uses fluorescencequenching detection technology to convert the optical signal of theinteraction between oxygen molecules and fluorescent molecules intoelectrical signals.Through 3D algorithms, stable and sensitive oxygenconcentration or oxygen partial pressure changes are obtained.Compared with the second generation electrochemical measurementtechnology, the LH-DY12 fluorescent dissolved oxygen sensor measureshigher, is plug-and-play and does not require the addition of any chemicalreagents.it is an ideal choice for industries such as chemical industry,.biomedicine,nuclear power,sewage and wastewater treatment, andsmart aquaculture. ldeal for water quality testing.
