Online dissolved oxygen Analyzer
Key Specifications：
✅Range 0-20mg/L(Customisable)
✅RS485/4-20AM output
✅Fluorescence method
✅Plug and play easy to operate
✅High and low limit alarms relay output
The optical dissolved oxygen Analyzer employs internationally leading fluorescence technology, which operates on the physical principle of specific substances quenching active fluorescence. The significant advantages of this fluorescence method for measuring dissolved oxygen include: no oxygen consumption, no flow restrictions, no need for electrolyte preheating, and no maintenance or frequent calibration required. Additionally, this method is unaffected by hydrogen sulphide interference and offers exceptional accuracy and stability. The sensor is equipped with an integrated temperature sensor, enabling automatic temperature compensation.
