CMS50-Pro Fingertip Pulse Oximeter – SpO₂, Pulse Rate & PI Monitor with Waveform Display.

The CMS50-Pro Pulse Oximeter is a compact and accurate fingertip device designed to measure blood oxygen saturation (SpO₂) and pulse rate quickly and reliably. It features a clear display showing SpO₂ values, pulse rate with bar graph, and pulse waveform, with optional PI value and battery power indication for enhanced monitoring.

Features

1. Display of SpO2 value, pulse rate value and bar graph, PI value (optional), pulse waveform.
2. Battery power indication (optional).
3. Low-voltage indication: the low power indication symbol appears when the voltage is too low to work.
4. Auto Power On & Auto standby.
5. The display mode can be changed (optional).
6. Adjustable screen brightness (optional).
7. PR sound prompt (optional), Sound prompt (optional).
8. Automatic direction-changing function (optional).
