CMS50Q1 Pediatric Pulse Oximeter – Fingertip Oxygen & Heart Rate Monitor.

The CMS50Q1 Kids Pulse Oximeter is a compact and safe device designed to measure blood oxygen saturation (SpO₂) and pulse rate (PR) through a child’s fingertip. It provides quick, accurate readings with a clear display showing SpO₂, pulse rate, and a bar graph, along with a pulse waveform for heart rhythm monitoring.

Features

1. SpO2 value display
2. Pulse rate value display, bar graph display
3. Pulse waveform display
4. The display mode & Screen brightness can be changed
5. Voice prompt for over-limit and low battery(optional)
6. PR sound indication(optional)
7. Low-voltage indication: low-voltage indicator appears before working abnormally which is due to low-voltage
8. Automatically power off function: when the device is under the state of measuring interface. it will automatically power off within 5 seconds if the finger falls out of probe.
