The CMS50F Pulse Oximeter is a compact, wrist-worn device designed for continuous or spot-check monitoring of blood oxygen saturation (SpO₂) and pulse rate. Using advanced photoelectric technology, it delivers precise measurements suitable for hospitals, clinics, sleep studies, and home healthcare. The CMS50F features a bright, adjustable screen that displays SpO₂, pulse rate, pulse waveform, and bar graph indicators. It offers low-power alerts, over-limit alarms, and PR sound indication for enhanced usability. With integrated memory storage, it records data for later review or transfer to a PC via a wired connection. Additional features include a clock function, charging capability, and intuitive sound prompts for probe-off, low battery, or abnormal readings.
