As a certified medical device, the BW 320 wrist blood pressure monitor delivers precise measurement results. It has a large, easy-to-read display that clearly shows the values for systole, diastole, pulse as well as the date and time. In the event of cardiac arrhythmia, the integrated arrhythmia display alerts the user. In addition, all measured values are classified according to World Health Organization (WHO) ratings using the traffic light colour scale.
