Luminescence dissolved oxygen sensor

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
