CMS50D1-Pro Fingertip Pulse Oximeter – SpO₂, Pulse Rate & PI Monitor with Waveform Display.

The CMS50D1-Pro Pulse Oximeter is a compact and reliable fingertip device designed to measure blood oxygen saturation (SpO₂) and pulse rate quickly and accurately. It features a clear display with SpO₂ values, pulse rate, bar graph, and pulse waveform, with optional PI value display for enhanced circulation assessment.

Features

1. Display of SpO2 value.
2. Display of pulse rate value and bar graph.
3. Display of pulse waveform.
4. Automatic direction-changing function.
5. Screen brightness can be changed.
6. Low-voltage indication: the low power indication symbol appears when the voltage is too low to work.
7. Auto standby.
