Now you can easily rely on the Beurer Upper Arm Blood Pressure Monitor to give you an accurate measure of your blood pressure, just as your doctor would. Just attach the cuff to begin the measurement process, and the BM 16 does the rest. The results are displayed on the large, easy to read LCD screen. The date is interpreted according to the guidelines of the World Health Organisation. It has a heart rhythm detector to help you detect any irregularities in your heartbeat. With the 2x50 memory space, you can manage your date over a period of time.
