1.Introduction CMS50N 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. CMS50N 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
