OXLFF - A Lead-free O2 Sensor Like No Other

Introducing the OXLFF - a revolutionary NEW lead-free oxygen sensor that sets a new benchmark in performance, ease of integration and value proposition for gas instrument manufacturers.

The OXLFF has a number of features which differentiate it from other lead-free O2 sensors and change the game for gas instrument OEMs.

✅ Ultra-Fast Start-Up: a start-up time of less than 2 minutes from zero power - the only lead-free O2 sensor with this feature.

✅ Best-in-Class Baseline Offset: enhanced resolution and unrivalled baseline stability without compromise on performance - the best performing mainstream sensor at low levels of O2.

✅ Industry-Leading T90 Response: a typical T90 of less than 2 seconds - the fastest lead-free oxygen sensor on the market.

✅ Exceptional Resistance to Pressure Changes: Up to 10x less sensitive to pressure changes than traditional sensors - a first for a lead-free O2 sensor.

✅ Unparalleled Recovery Speed: a recovery time which mirrors its rapid response - the fastest recovery of any lead-free O2 sensor currently available.

✅ 5+ Year Lifetime: No consumables and up to five times the lifespan of some other O2 sensors - unrivalled for a sensor with the features the OXLFF offers.
