Blood Oxygen Monitor Fast Rapid Reading Finger Pulse Oximeter Mini SpO2 Monitor Oxygen Saturation Monitor Measuring Gauge Device

Features:
Color LED display is a painless and noninvasive device, which shows you:
Blood oxygen saturation or SpO2 level: it shows the percentage of hemoglobin carrying oxygen in the blood. The normal level is 95% or higher and the power consumption is low. It can work continuously for 24 hours.
Display range of blood oxygen value: 70-100% pulse rate value - display range: 30-240 BPM
Resolution: blood oxygen saturation 1%, pulse 1bpm
Accuracy: the 70% - 100% segment of blood oxygen saturation is 1%, less than 70%, undefined, and the pulse rate is 2bpm or 1%, whichever is higher
Anti environment light intensity, weak perfusion
Display format: liquid crystal display: blood oxygen saturation display: 70-100%, four directions, eight modes (upper, lower, left and right fonts respectively)
Three step operation is simple and fast
Remove the back cover and install the two AAA batteries.
Point your finger at the red light, insert it and wait for the oximeter to turn on.
Read the results in 8 to 10 seconds.
Immediate and accurate results (seconds)
