A compact and cost-effective zirconia oxygen transmitter to measure percentage level oxygen in combustion processes, excess air monitoring, bakery ovens, and many more applications.

The unit is configurable to measure either 0-25 % or 0-100 % oxygen and offers manual or automatic calibration to suit the customer’s needs.
The probe can be mounted directly on a stainless steel or aluminum electronic housing, and the OXY-FLEX Series is easy to install and integrate into existing systems as no specialist software is required.

Typical applications include; combustion control of industrial boilers, burning oil, gas, coal or biomass; composting probes and duct monitoring systems.
