- Can measure SpO2 and Pulse Rate accurately
- SpO2 and Pulse Rate display, bar graph display
- Battery voltage low indication
- Automatic shut off
- SpO2 measurement range: 0%~100%
- Accuracy: 70%~100%: ±2%
- 0%~69%: unspecified
- PR measurement range: 30bpm~250bpm
- Accuracy: ±2bpm or ±2%, whichever is greater.
- 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: ≤25mA
- Power supply: two “AAA” batteries
