  • Low Power, Long Life
  • Suitable for Battery-Powered Use

The UV Flux Oxygen sensor measures ambient O2 levels in 0-25%. Unlike traditional electrochemical oxygen sensors, by using UV light is sensor has a lifetime measured in years instead of months. This makes it perfect for portable, medical, industrial or many other applications.

The UV Flux sensor is both oxygen pressure and temperature compensated, enabling accurate operation over a wide environmental range without the need for additional system components.
