FST100-DO202A Smart Dissolved Oxygen Sensor

The intelligent dissolved oxygen sensor consists of three parts: an optical path system, a fluorescent sensitive film, and an optical detection system. After the probe is inserted into the test medium, oxygen in the medium immediately diffuses into the organic silicon molecular layer and quickly reaches equilibrium. Apply modulated green light to the fluorescent layer, causing the fluorescent molecules to produce red fluorescence. Fluorescent molecules are quenched upon encountering oxygen, and the fluorescence intensity and response time vary with the oxygen content. Detecting changes in fluorescence response time to determine oxygen content.

●Adopting optoelectronic technology, with low maintenance rate and high reliability

●No oxygen consumption, no flow rate requirement, capable of static water measurement

●Good compatibility, the sensor provides 485 digital signals based on MODBUS protocol

●Good stability, excited by green light, greatly slows down the decay rate of fluorescent substances, and has a longer lifespan

●Strong anti-interference ability, fully digital processing technology and stainless steel shell shielding

●automatic temperature compensation

[Scope of Application]

Fluorescent dissolved oxygen sensors are widely used in water quality monitoring scenarios such as aquaculture, sewage treatment, rivers, lakes, and drinking water.
