Capturing repeatable, correct readings using the A&D UB-542 Automatic Wrist Monitor is made easy with A&D technology:

A&D WHO Blood Pressure Indicator.

  • A&D initially established the simple “traffic light” indicator system for blood pressure monitors in 2003
  • This basic indicator helps users quickly identify whether their readings are low, normal, or high according to the WHO guidelines

The A&D UB-542 also profits from a large memory function, enabling the recording of up to 90 recordings for two users. It also integrates the average value feature of the stored data, as well as the WHO Blood pressure classification indicator to allow the users to better regulate their management programs.

It also comprises of A&D’s IHB/Circadian Rhythm analysis technology, established by A&D in 2001 and presently found on A&D’s complete range of blood pressure monitors. This A&D revolutionary technology is currently used globally assisting in the opportunistic detection of arrhythmias — which include Atrial Fibrillation (Afib).

The Japanese design and dependable quality of the UB-542 enable A&D to provide users a five-year warranty (excluding cuff and batteries).
