Ultrasonic Oxygen Sensor Gasboard-8500FS-L240

Ultrasonic Oxygen Sensor

Gasboard-8500FS-L240 is Cubic's ultrasonic technology 5-in-1 combined sensor solution to measure flow rate, oxygen concentration, temperature, pressure and humidity. It is suitable in binary gases for medical ventilators to support the global pandemic situation due to Corona virus outbreak. The measured flow rate range of Gasboard-8500FS-L240 can be up to 240L/min. Benefit from ultrasonic technology and principle of TOF (time of flight) measurement, Gasboard-8500FS-L240 has excellent performances with advantanges of high accuracy, fast response, no drift, no need for routine calibration and maintenance-free, etc.. Gasboard-8500FS-L240 can be widely used in high-flow nasal cannula oxygen therapy ventilation, positive airway pressure ventilation, anesthetic ventilator and other medical equipments related to breath.
