Cubic Sensor’s Gasboard-8500FS-X200 is a sensor solution specially developed to quantify flow rate, temperature, humidity and oxygen concentration. The ultrasonic technology enables 4-in-1 combined sensor operation. The instrument is suitable in binary gases for medical ventilators, assisting in the global pandemic that has resulted from the COVID-19 outbreak.

The Gasboard-8500FS-X200 has a flow rate in the range of 240 L/minute. The system has been designed to have ultrasonic technology as well as TOF (time of flight) measurement. The system delivers remarkable performance such as a quick response, no drift, high precision, no routine calibration, maintenance-free operation and more.

The Gasboard-8500FS-X200 can be extensively employed in high-flow nasal cannula oxygen therapy ventilation, anesthetic ventilator, positive airway pressure ventilation and medical equipment related to breathing.
