Brief introduction

1.Introduction
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 is applicable for use in plateau area, community healthcare, oxygen  bar, Fitness clubs, physical training room, family and medical institution, etc.  

2.Features
1) Can measure  SpO2 and Pulse Rate accurately
2) SpO2 and Pulse Rate display,bar graph  display 
3) Battery voltage low indication
4) Shut off automatically when  no signal
3.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% 
PR: 1bpm
Measurement  Performance in Weak Filling Condition: SpO2 and pulse rate can be shown  correctly when pulse-filling ratio is 0.4%. SpO2 error is ±4%, pulse rate error  is ±2 bpm or ±2%, whichever is greater.
Resistance to surrounding light: The  deviation between the value measured in the condition 
of man-made light or  indoor natural light and that of darkroom is less than ±1%.
Working current:  ?25mA
Power supply: two ?AAA? batteries
Safety classification: type BF  applied part
