OLED Fingertip Pulse Oximeter Finger Blood Oxygen SpO2 PR Heart Rate Monitor,softbag,rope,batteries,FDA

1.Instruction
CMS50NA 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.
CMS50NA 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,Pulse Rate waveform and bar graph display
3) Battery voltage low indication
4) The display mode can be changed.
5) Screen brightness adjustable

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: ≤30mA
Power supply: two “AAA” batteries
Safety classification: type BF applied part
