Oxygen Optode 4835
The AADI Oxygen optode was the first and only to measure dissolved oxygen for years without drift - now it is one of the fastest!
The Oxygen optode is designed to measure absolute oxygen concentration and % saturation. The optode can be used from streams to deep sea, from fish farms to waste water and from polar ice areas to hydrothermal vents. The lifetime-based luminescence quenching principle offers the following benefits:
Response time <8 sec (63%)
High accuracy
Not stirring sensitive (it consumes no oxygen)
Lower fouling sensitivity
Measures absolute oxygen concentrations without repeated calibrations
Better long-term stability
Hot water monitoring
Less affected by pressure
Not sensitive to H2S
Not freezing sensitive
