The Medisana BU 535 is a blood pressure monitor that allows you to measure your blood pressure in no time. The device offers storage space for 120 measurements and the possibility to set 2 user profiles. If the cuff is not properly positioned around your arm, the blood pressure monitor will give you a notification. To show accurate values, the device calculates an average over the last 3 measurements. In addition, the device switches off automatically in the event of inactivity, so that you do longer with the batteries.
