Home upper-arm BP monitor

The EC2WORLD B21 is an automatic digital blood pressure monitor designed for home use. It inflates and measures with a single button press and stores up to 120 readings each for two users. A wide-range cuff fits arm circumferences from 8.7 to 15.7 inches. Live-voice broadcast with adjustable volume announces results for easier reading.

Check cuff fit and power

Verify that the intended user’s upper-arm circumference falls within the 8.7 to 15.7 inch range before ordering. The device runs on batteries; no mains adapter is mentioned in the specifications. Ensure the arm can be positioned at heart level and that the cuff can be wrapped snugly following the supplied instructions for accurate results.

Suits two-person households needing voice guidance

Households where two people track readings separately will benefit from the dual 120-memory slots and quick user switching. Users who prefer audible results gain from the talking function. Buyers requiring data export to a phone or computer, a backlit display, or a cuff sized outside the stated range should look at other models.

Questions about this item

What is included with the B21 monitor and what must be purchased separately?

The box contains the monitor, a cuff fitting 8.7 to 15.7 inch arms, and a storage bag; it runs on batteries or a Micro USB cable, neither of which are supplied.

Which memory version should I choose, 2×120 or 2×250?

This B21 model provides 2×120 memory, storing 120 readings for each of two users; the 2×250 version belongs to a different model.

What does the 15.7 inch cuff range mean for daily use?

The cuff fits upper arms from 8.7 to 15.7 inches in circumference, covering most adult arms so you can wrap it once without needing a separate size.
