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. PyroScience recommends using their OXCAL zero oxygen calibration capsules which can be purchased directly from us. Please note that all contactless sensors require fiber optic cables and other accessories (depending on a sensor type) for complete systems. View the list of all necessary accessories here.

 

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.
