The Omron 5 Series will also let you know how your reading compare with internationally recognized guidelines for normal blood pressure with the BP Level Bar. The 5 Series also features Advanced Accuracy that automatically displays the average of the last 3 readings taken within 10 minutes. This model is quick and easy and has a few more features than the 3 Series home blood pressure monitor, like dual settings for two users, memory storage space for up to 100 readings (50 readings for each user) and a wide range D-Ring cuff that fits standard and large arms 9 to 17 inches in circumference. The 5 Series® home blood pressure monitor (BP742N) with Omron’s Advanced Accuracy helps ensure consistent, precise readings.
