Gasboard-8500D-RH Ultrasonic Oxygen Concentration Sensor for Medical Device Applications

The Gasboard-8500D-RH is an ultrasonic oxygen concentration sensor is used to measure oxygen concentration in binary gasses.
The Gasboard-8500D-RH uses a time-of-flight measurement principle that can provide a stable and accurate measurement that is free from drift and does not require calibration.


  • Ultrasonic measurement of oxygen concentration (flow range 0-80 liters per minute)
  • Time of Flight measurement principle ensures continuous measurement free of drift and removes the need for regular calibration
  • Excellent measurement stability, high accuracy and fast response in all medical device application environments
  • Full scale temperature and humidity compensation
  • Optimized Price-Performance Ratio
  • Easily integrated into ventilators, compact size
