Brief introduction

1.Introduction

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) Four directions and six modes

5) Screen brightness adjustable

6) 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: ≤30mA

    Power supply: two “AAA” batteries

    Safety classification: type BF applied part
