Product features:
1. Color TFT display
2. Display range of blood oxygen value: 70-100% display range of pulse rate value: 30-240bpm
3. Resolution: oxygen saturation is 1%, pulse rate is 1bpm
4. Accuracy: ± 1% in 70% ~ 100% of SpO2, no definition in less than 70%, the pulse rate is ± 2bpm or ± 1%, the larger value is taken
5. Power requirements: 2 No.7 1.5V alkaline batteries
6. Strong resistance to ambient light and weak perfusion
7. Display format: LCD display: blood oxygen saturation display: 70 - 100%, four direction changes, eight modes of display; (up, down, left and right           fontchanges)
    Pulse rate display: 30-240 BPM, 3-digit seven segment digital display;
    Pulse wave display: bar graph display;
    Low battery voltage indication: LCD symbol.
8. Power requirements: 2pcs *(No.7 ) 1.5V alkaline batteries, voltage range: 2.6-3.6v.
9. Power consumption: less than 30 ma.
10. Resolution: SpO2 ± 1%, pulse rate ± 1 bpm.
11. Measurement accuracy: ± 2% in 70% - 100% oxygen saturation, undefined in less than 70%, and ± 2 BPM pulse rate.
12. Measurement performance under weak perfusion: it can correctly display blood oxygen and pulse rate when the pulse filling degree is 0.5%.
13. Anti interference ability of ambient light: compared with the measurement value in dark room, the deviation of blood oxygen measured under indoor natural light and existing lighting source is less than ± 1%.
14. With function switch, it will automatically shut down after 8 seconds without finger insertion.
