Measure and Save Blood Pressure with Wearable Monitor

The A&D LifeSource Digital Wrist Blood Pressure Monitor simplifies monitoring your blood pressure with a single push of a button. This blood pressure wrist monitor is smaller, lighter and more compact than most other wrist monitors, making it ideal for travel and routine use. Unlike other monitors that measure blood pressure during deflation of the cuff, the Travel Size wrist monitor measures blood pressure during cuff inflation for a faster, more comfortable reading. The automatic memory keeps your last 60 blood pressure measurements for effective tracking.

The average reading feature automatically calculates the "average" of the total readings stored in memory. The UB-521 also has the Irregular Heartbeat feature. This feature provides blood pressure and pulse rate measurements even when an Irregular Heartbeat occurs and alerts the user. 

  • Irregular Heartbeat Indicator
  • Saves up to 60 recent measurements and displays overall average of compiled results
  • Powered by LR03 or AAA batteries


  • Blood Pressure Monitor
  • (2) AAA Batteries
  • Instruction Manual
