LED Finger Pulse Oximeter Blood Oxygen SpO2 PR Heart Rate Monitor
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.

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
