The UltraMaxO2 is a handheld device designed for oxygen concentrator service technicians to efficiently check patient O2 concentrators. It integrates oxygen, flow, and outlet pressure measurements, eliminating the need for a traditional electrochemical sensor, thus reducing maintenance and ownership costs.

• Calibration Verification: A button verifies the unit's calibration, displaying "cal ver" for confirmation. Error codes indicate calibration issues.
• Ultrasonic Sensor: Eliminates the need for in-field calibration and sensor replacement, reducing ownership costs.
• Integrated Measurements: Combines pressure, %O2, and flow measurements in one device, simplifying equipment needs.
• Pressure Measurement: Easily check outlet pressure by covering the outlet port, switching the display from %O2 & flow rate to pressure.
• Unit Display Change: Pressure units can be switched between PSI and kPa via a switch inside the battery door.
• Design and Durability: Lightweight, durable, and easy to transport with a protective silicone case.

• Quick Set-Up & Readouts: Easy connection and clear LCD display for fast readings.
• Reduced Cost of Ownership: Long-lasting ultrasonic sensor reduces maintenance costs.
• Confidence in Delivery: Reliable measurements ensure accurate oxygen delivery.
