SST's All-In-One Oxygen Analyzer-Image

The OXY-Flex Oxygen Analyzer is the latest creation from SST's creative and experienced engineering team of experts. The OXY-FLEX Oxygen Analyzer is an all-in-one gas detection system that combines SST's unique zirconium dioxide oxygen sensors with very low cost interface electronics. The OXY-Flex is the ideal solution for customers with a requirement for an oxygen sensor and electronics combined for use in industrial applications, especially combustion proccesses.

SST's oxygen sensors are used in fuel tank gas inerting systems in various aircraft including Boeing and Airbus, as well as the biomass boiler and gas combustion market where they are fitted to improve heating efficiency of boilers and reduce harmful emissions. Although these are the primary target markets for these products, SST have quickly learned over the last few years that their oxygen sensors are suited to a large number of alternative and exciting applications due to the flexibility and capability of the sensor. The sensors can prolong the life of fruit, vegetables and other perishable goods by monitoring the oxygen levels in the storage and transportation environments. They can also be used in composting, agriculture and medical applications, to name just a few.
