LOHAND - Digital Optical Dissolved Oxygen Sensor LH-DY12
Brand: Lohand
Model: LH-DY12
Introduction
The LH-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.
Compare 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 wastetwater treatment,and smart aquaculture.Ideal for water quality testing.
