Luminescent Dissolved Oxygen Technology
This sensor adopts the optical measurement principle based on the quenching effect of fluorescent substances. It calculates the dissolved oxygen concentration by exciting the fluorescent dye with a blue LED and detecting the quenching time of the red fluorescence.The work of replacing the electrolyte or diaphragm is avoided, and the lossless measurement is realized.
PPM, A Large Quantity
The measurement range is 0-20mg/L, suitable for various water environments such as fresh water, seawater and high-salinity wastewater. It is equipped with an internal salinity compensation function to ensure data accuracy.
Anti-interference Design
It is not affected by hydrogen sulfide, flow rate changes or solution fouling, and is particularly suitable for monitoring in complex working conditions such as sewage treatment and aquaculture.
High Precision
IP68 Protection Grade
Strong environmental adaptability
Product advantages
It is equipped with multiple parameter measurement programs to choose from, and the measurement can be automatically recognized by replacing the sensor. (For example: pH, conductivity, salinity, turbidity, SS, chlorophyll, COD, ammonium ion, nitrate, blue-green algae, phosphate, etc.)
The dissolved oxygen measurement accuracy reaches ±2%, and the temperature compensation accuracy is ±0.5℃, making the measurement data very reliable.
With a fully sealed waterproof body design, it can withstand immersion in a water depth of 1 meter for 30 minutes. With dust-proof and anti-corrosion capabilities, making it suitable for outdoor operations and industrial sites.
Built-in temperature sensor, air pressure and salinity compensation, automatically correcting the influence of environmental variables. When monitoring seawater, the salinity compensation range reaches 0-40ppt, and the temperature compensation accuracy is ±0.1℃.
Virtually no Maintenance Required
Ultra-long Battery Life
Multi-parameter Automatic Compensation
As this is an optical dissolved oxygen probe, there is virtually no maintenance required — as there are no membranes to replace, no electrolyte solution to replenish, and no anodes or cathodes to clean.
The battery life in continuous working mode is ≥72 hours, making it suitable for long-term outdoor monitoring.
Built-in temperature sensor, air pressure and salinity compensation, automatically correcting the influence of environmental variables. When monitoring seawater, the salinity compensation range reaches 0-40ppt, and the temperature compensation accuracy is ±0.1℃.
