The CMS50Q1 Pulse Oximeter is a compact, intelligent device designed for accurate measurement of blood oxygen saturation (SpO₂) and pulse rate through the fingertip. Using advanced photoelectric technology, it provides clear, real-time readings suitable for hospitals, clinics, and homecare applications. The device features SpO₂, pulse rate, bar graph, and pulse waveform displays, allowing users to assess oxygen and pulse conditions quickly. Its display and brightness can be adjusted for user comfort, and optional features include PR sound indication and voice prompts for over-limit and low battery alerts. A built-in low-voltage indicator ensures reliability, while the automatic power-off function conserves energy when not in use. Designed for convenience and accuracy, the CMS50Q1 is ideal for both professional and personal health monitoring.
