Format: OLED Display;
SpO2 Measuring Range: 0% - 100%;
Pulse Rate Measuring Range: 30 bpm - 250 bpm;
Pulse Wave Display: columniation display and the waveform display.
Power Requirements: 2 × 1.5V AAA alkaline battery (or using the rechargeable battery instead), adaptable
2)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%. 8)It is equipped with a function switch. The Oximeter can be powered off in case no finger is the Oximeter within 5 seconds. 9)Optical Sensor Red light (wavelength is 660nm, 6.65 mW) Infrared (wavelength is 880nm, 6.75 mW) The pulse oxygen saturation is the percentage of HbO2 in the total Hb in the blood, so-called the O2 concentration in the blood. It is an important bio-parameter for the respiration. For the purpose of measuring the SpO2 more easily and accurately, our company developed the Pulse Oximeter. At the same time, the device can measure the pulse rate simultaneously. The Pulse Oximeter features in small volume, low power consumption, convenient operation and being portable. It is only necessary for patient to put one of his fingers into a fingertip photoelectric sensor for diagnosis, and a display screen will directly show measured value of Hemoglobin Saturation.
