Ultra-small Ultrasonic Oxygen Sensor
Gasboard-6500HMGasboard-6500HM

Cubic Gasboard-6500HM is an ultra-small ultrasonic oxygen sensor specifically developed for portable oxygen concentrators (POCs). Utilizing ultrasonic technology and time-of-flight (TOF) principle, it delivers highly accurate measurements of both oxygen concentration and flow rate. Gasboard-6500HM’s ultra-small size enables easy integration into space-constrained POCs, while its fast response ensures reliable and precise monitoring under pulse mode. In addition, featuring full temperature compensation, Gasboard-6500HM ensures consistent measurement accuracy across varying environmental conditions. With its no-moving-parts design, Gasboard-6500HM provides maintenance-free operation and ensures a long service life over 15 years. Gasboard-6500HM offers a precise, reliable and cost-effective solution for portable oxygen concentrator applications.
