The Beurer Series 800 upper arm blood pressure machine has an XL LCD display to easily read your blood pressure and the color-coded risk indicator helps quickly interpret it. Measure your blood pressure and heart rate in one easy-to-use device – if an irregular heartbeat is detected by the blood pressure monitor, an alarm will sound. It also features an averaging function of all saved measurements. Sync blood pressure readings to your smartphone via Bluetooth with our free Health Manager Pro app – no more manual recording of your results. The Series 800 can also store 100 readings for 2 users on the device and the blood pressure cuff fits most sized arms from 8.7 to 17.3 inches.
