Fingertip Pulse Oximeter CMS50D-BT SPO2 Monitor Blood Oxygen 24Hours Record

Features
1) Display of SpO2 value, PR value, bar graph and pulse waveform.
2)Low-voltage indication: the low power indication symbol appears when the voltage is too low to work.
3)Automatic standby function.
4)Display direction can be changed automatically.
5)PR sound indication (wired equipment).
6)Sound prompt function: over-limit prompt of measured value, finger-out prompt, low power prompt (wired equipment).
7)Data memory function.
8)The data can be uploaded to the terminal equipment by wired mode.
