Technical Specifications
1)Display Format: OLED Display;
SpO2 Measuring Range: 0% - 100%;
Pulse Rate Measuring Range: 30 bpm - 250 bpm;
Pulse Wave Display: columiation display and the waveform display.
2)Power Requirements: 2 ×1.5V AAA alkaline battery(or using the rechargeable batteryinstead), adaptable range: 2.6V~3.6V.
3)Power Consumption:Smaller than 30mA.
4)Resolution: 1% for SpO2 and 1 bpm for Pulse Rate.
5)Measurement Accuracy: ±2% in stage of 70%-100% SpO2, and meaningless when stage being smaller than 70%. ±2 bpm or±2% (select larger) for Pulse Rate.
6) 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%(select larger).
7) 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%.
