Oxygen Sensors

PyroScience oxygen sensor systems are based on innovative, high-precision optical detection technique called REDFLASH technology. The sensor designs range from robust probes and microsensors to contactless sensors for closed containers as well as a one of a kind solvent-resistant probe for many polar and non-polar solvents. Pair these up with a compatible optical device and necessary accessories for complete sensor systems.

​We offer complete plug-and-play sensor systems and OEM type solutions for a variety of scientific and industrial applications.
