Fibre-Optic Oxygen Micro Sensors
Fixed Fibre-Optic Oxygen Micro Sensors
The fibre-optic oxygen sensors from PyroScience feature no oxygen consumption, no stirring sensitivity, an extremely long shelf time, resistance to corrosive environments (e.g. seawater) and are suitable for multiple applications in gas, water and aqueous samples.

Retractable Fibre-Optic Oxygen Micro Sensors
The fibre-optic oxygen sensors from PyroScience feature no oxygen consumption, no stirring sensitivity, an extremely long shelf time, resistance to corrosive environments (e.g. seawater) and are suitable for multiple applications in gas, water and aqueous samples. They consist of an optical fiber (230 µm) with a sensor tip diameter of approximately 50-70 µm. Microsensors are perfectly suited for measurements in small samples and for profile measurements (e.g. in sediments, soils, plant tissue, biofilm) with high spatial resolution (microprofiling).
