Finger Pulse Oximeter SPO2 Sensor Pulse Heart Rate Meter Blood Oxygen O2 Monitor

CMS50M Pulse Oximeter is a portable equipment adopting advanced technology. It mainly checks SpO2 and PR value through the finger, which provides advanced, non-invasive and scientific means for quantitative measurement of oxygen saturation. 
CMS50M Pulse Oximeter applies for plateau area, community healthcare, oxygen bar, fitness clubs, physical training room, family and medical institution, etc.

Finger Pulse Oximeter SPO2 Sensor Pulse Heart Rate Meter Blood Oxygen O2 Monitor Features:

1)  Can measure SpO2 and Pulse Rate accurately
2)  SpO2 and Pulse Rate display, bar graph display 
3)  Battery voltage low indicator
4)  Shut off automatically when no signal

Performance:

SpO2  measurement range: 0%~100%
Accuracy: 70%~100%: ±2%
 0%~69%:  unspecified
PR measurement range: 30bpm~250bpm
Accuracy: ±2bpm or ±2%,  whichever is greater.
Resolution: 
SpO2: 1%
