The CMS50H Pulse Oximeter is a multifunctional fingertip device designed to measure blood oxygen saturation (SpO₂) and pulse rate with precision and convenience. Featuring an operation menu for customized settings, it displays SpO₂, pulse rate, pulse waveform, bar graph, and perfusion index (PI) values on a clear screen. The device supports automatic display rotation, ensuring easy viewing from any angle. Additional features include pulse rate sound indication and voice prompts for over-limit, low battery, and finger-out alerts, providing users with real-time feedback for safer monitoring. With built-in data storage, the CMS50H can record measurement history and upload stored or real-time data to a computer for analysis.
