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.
1) Can measure SpO2 and Pulse Rate accurately
3) Battery voltage low indication
SpO2 measurement range: 0%~100%
Accuracy: 70%~100%: ±2%
PR measurement range: 30bpm~250bpm
Accuracy: ±2bpm or ±2%, whichever is greater.
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
Dimension: 57mm(L) × 34mm(W) × 31mm(H)
