The PM 100 Connect pulse oximeter by Medisana measures the saturation of oxygen in the blood (SpO2) and the heart rate for a reliable health check at home or on the road. It has a range of between 70% and 100% SpO2, which is more than sufficient for all applications, both medical and sports. This also applies to the heart rate, which has a range of between 30 to 235 beats/min. The PM 100 oxygen level meter displays the results as desired in bar or wave graph. The display rotates automatically, so that the results are always direct and clear to read for the greatest ease of use. Moreover, the two AAA batteries supplied last for a long time, partly due to the economical, but clear OLED screen. This PM 100 Connect saturation meter has a Bluetooth connection with the VitaDock+ app for
