Features: 1) Blood oxygen saturation value display 2) Pulse rate value, bar graph display 3) Pulse waveform display 4) can change the display mode 5) can automatically change the display direction 6) Low battery indicator 7) Low battery voltage indication: The battery low battery indicator appears before the battery voltage is low enough to work properly. Descriptions: The pulse oximeter uses photoelectric oximetry combined with volumetric pulse stimometry to detect human blood oxygen saturation and pulse through fingers. This product is suitable for non-invasive monitoring of blood oxygen saturation and pulse rate in hospitals and homes.
