YIMI LIFE Fingertip Pulse Oximeter

The oxymeter consists of probe, electronic circuits, and display and plastic enclosures. And one side of probe is designed to locate light emitting diodes
and a light detector (called a photo-detector). Red and Infrared lights are shone through the tissues from one side of the probe to the other. Then parts of the light emitted absorbed by blood and tissues. The light absorbed by the blood varies with the oxygen saturation of haemoglobin. After that, th photo-detector detects the light volume transmitted through the tissues which depends on blood pulse, Hereafter, the microprocessor calculates a value for the oxygen saturation (SpO2). The subject device is a reusable device, and need to reprocess as suggested in the user manual after each use. And the device is intended to be used on the finger, and powered by 2pcs 1.5V AAA battery.
YM101 display the measuring results on 1.5inch LED screen, and the backlight of the three models are red, white and green respectively. And the screen of YM201 and YM301 are 0.96inch OLED and 1.3inch OLED. Additionally, battery indicator and pulse waveform can be displayed on YM201 and YM301.
Easy to Use
1. Open oxymeter
2. Place your finger in the oxymeter
3. Press the power button
