Ultrasonic Oxygen Sensor

Gasboard-8500FS-L40 is ultrasonic oxygen sensor and can measure flow rate, concentration, temperature, humidity in binary gases. The oxygen flow rate range is 0 to 40L/min. By adopting ultrasonic detecting technology and principle of TOF (time of flight) measurement, Gasboard-8500FS-L40 sensor has remarkable performances: high accuracy, fast response, continuous monitoring, no drift, no need routine calibration, maintenance-free, etc. Gasboard-8500FS-L40 sensor is very suitable for neonatal anesthesia machine and other medical equipment
