The Omron RS1 automatic wrist blood pressure monitor is simple, portable, and accurate for all body sizes. Measuring blood pressure at the wrist is a great alternative if you find upper arm cuffs either too small or uncomfortable. The RS1 cuff fits wrists with a circumference of 13.5 to 21.5 cm, which covers almost everyone. Just put it on, raise your wrist to heart level, and wait for your result. Small and compact, take the RS1 with you and keep track of your blood pressure throughout the day.
