Optical Oxygen Sensors

All PyroScience optical oxygen sensors utilize patented REDFLASH technology that guarantees fast and accurate oxygen measurements with no sample consumption. These optical sensors work well in a variety of different gaseous, aqueous and semi-solid samples in many types of applications, including challenging environments like organic solvents, microfluidics and high-throughput screenings. These sensors feature no stirring sensitivity, long shelf life and resistance to corrosive environments (e.g., seawater).
 
Choose from a variety of fiber-optic and contactless oxygen sensors as well as solvent-resistant oxygen probes. If you have difficulty identifying the best possible sensor for your application, consider getting one of our starter kits that includes a few different sensor types, or contact us. We will be happy to discuss your application in more detail to help you find the best possible system and sensor solution.
