Medisana electric underblanket HU 662 61220

This Medisana saturation meter PM 100 79455 accurately measures the saturation of oxygen in the blood and the heart rate. Both measured values can be viewed in 6 different ways on the clear OLED display, as a bar chart or in waveform. In addition, the brightness of the display can be cleverly adjusted in 10 levels. The battery level indicator informs you about the battery status. The PM 100 saturation meter switches off automatically after eight seconds and is a handy device to use every day. It is not only suitable for home use, but also for travel thanks to the simple "one touch" operation.
