The O2 MicroOptode is designed for research within respiration, bulk and bioreactors as well as environmental and biomedical sciences
The O2 optode signal was not sensitive to variations in water flow or light exposure. However, the response time was affected by the direction of the flow. When the sensor tip was exposed to a flow from the back rather than the front, the response time increased by 37%. The meter's ...

We measured average O2 in each treatment group for all populations by using a fiber-optic O2 optode that provides real-time O2 monitoring (FireStingO2, PyroScience, GmbH, Germany) (raw data for average pO2 measured for each population can be found in the Source Data file). Finally, we ...
Back on shore, the final O2concentration values were calculated following Bittig et al. (ref.18) from the optode, calibration and in situ pressure data that was derived from the depth where each lander deployment was made. Time stamps in the optode data were compared to the lander computer ...
The Aanderaa Oxygen Sensor measures absolute oxygen concentration and % saturation. The o2 meter can be used for streams, the deep sea, fish farms, wastewater, and polar ice areas to hydrothermal vents. Read more on the oxygen optode working principle us
O2 Flux Optode By applying a transparent test membrane of defined diffusion properties between two layers of optical chemical oxygen sensors, O2 optodes, the measurement of oxygen diffusion, the oxygen flux, across the membrane becomes possible.1 The o... D. W. Lübbers,T. Kster,G. A. Hols...
The June 2015 cruise took place onboard the F.S. Alkor (GEOMAR) in the Gotland basin (Fig.1). Water samples were collected with Niskin bottles via deployment of a SeaBird CTD system. Dissolved oxygen concentration (DO) profiles were taken from the CTD optode and calibrated against DO concen...

The raw O2 microsensor output was calibrated to the dissolved O2 concentration in µmol O2 L−1 in water and ice using a two-point calibration. The first point was obtained from the in situ O2 concentration in the water as measured by the optode, and the second point was obtained in ...
