CMS50D1 Fingertip Pulse Oximeter – SpO₂ & Pulse Rate Monitor with Pulse Waveform Display.

The CMS50D1 Pulse Oximeter is a compact and easy-to-use device for measuring blood oxygen saturation (SpO₂) and pulse rate through the fingertip. It features a clear display with SpO₂ values, pulse rate, bar graph, and pulse waveform, along with adjustable screen brightness and an automatic display rotation. The device also includes a low-voltage warning and auto-standby function for convenience and safety.

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.
