IntroductionThe CMS50EA Pulse Oximeter adopts Photoelectric Oxyhemoglobin Inspection Technology in accordance with Capacity Pulse Scanning & Recording Technology, which can be used to measure human oxygen saturation and pulse rate through finger. The device is suitable for being used in family, hospital, oxygen bar, community healthcare and physical care in sports, etc. (It can be used before or after exercise, but not recommended to use during exercising).
Features1)Integrated SpO2 sensor and display module
2)Small in volume, light in weight and convenient in carrying
3)Easy to operate, low power consumption
4)Operation menu for function settings
5)SpO2 value display
6)Pulse rate value display, bar graph display
7)Pulse waveform display
8)Display direction can be changed
