If your upper arm circumference is between 16.5″ and 23.6″, standard cuffs (typically 9″–17″) are too small for you — and a cuff that's too small will read higher than your actual blood pressure, sometimes significantly. The UA-789AC ships with an extra-large cuff purpose-built for larger arms, paired with a high-speed inflation motor that makes the measurement faster and more comfortable. The accuracy is clinically validated to ANSI/AAMI SP-10 standards (±3 mmHg pressure, ±5% pulse). You get 60-reading memory with date/time stamps, automatic last-3 averaging, irregular heartbeat detection, a pressure rating indicator that classifies your reading against medical guidelines, three programmable reminders so you measure at consistent times each day, and a large backlit LCD. The included AC adapter means you don't burn through batteries — a real advantage for daily monitoring. What you won't get: Bluetooth syncing, multi-user memory, or app-based trend tracking. If those features matter, the Omron BP7255 ($69.99), BP7360 ($87.43), or BP7465 ($99.99) offer connected monitoring with standard 9″–17″ cuffs. But none of those monitors support a cuff larger than 17 inches. If cuff fit is your problem, the UA-789AC is the solution — and no amount of Bluetooth or AFib screening features matters if your cuff doesn't fit correctly. Why you'd choose this blood pressure monitor Extra-Large Cuff — 16.5″ to 23.6″ The included cuff fits upper arm circumferences from 16.5 to 23.6 inches (42–60 cm) — the largest home blood pressure cuff widely available. Proper cuff fit is the single biggest factor in accurate home readings. A cuff that's too small reads artificially high; too large reads low. This monitor eliminates that problem for larger arms. Clinically Validated Accuracy Validated to ANSI/AAMI SP-10 standards. Pressure accuracy is ±3 mmHg and pulse accuracy is ±5%. Uses oscillometric measurement with HeartWise™ technology that measures blood pressure on deflation for consistent results even when irregular heartbeats are detected. 60-Reading Memory + Last-3 Averaging Stores 60 readings with time and date stamps for single-user trend tracking. Automatically calculates and displays the average of your last 3 readings — giving you a more reliable snapshot than any single measurement. Irregular Heartbeat Detection The irregular heartbeat indicator alerts when an abnormal rhythm is detected during measurement. Unlike some monitors that simply flag an error, the UA-789AC still provides your blood pressure and pulse readings when irregularities are detected. AC Adapter Included A 120V AC adapter is included in the box for reliable plug-in home use — no batteries to replace for daily monitoring. Battery operation (4 AA, not included) is also available for portability, with approximately 120 measurements per set. 3 Programmable Reminders Set up to 3 daily reminders so you take readings at consistent times — critical for building a reliable blood pressure log. Consistency in timing is one of the strongest recommendations from medical guidelines for home BP monitoring. Large Backlit LCD Display Extra-large display (2.2″ × 2.8″) with 20mm character height and backlighting for easy reading in any lighting. Systolic, diastolic, and pulse are displayed simultaneously. Pressure rating indicator classifies your reading against medical standards. 5-Year Monitor Warranty A&D backs the monitor with a 5-year warranty (2 years on the cuff). Cuffs are not made with natural rubber latex. Compatible replacement cuffs are available for medium (9.0–14.6″) and large (12.2–17.7″) arm sizes. Tip: Tab to a reason and press Enter to expand the explanation. Press Escape to close. Who this monitor is perfect for Users with upper arm circumferences between 16.5″ and 23.6″ who cannot get accurate readings with standard 9″–17″ cuffs. Bariatric patients or anyone told by their clinician that cuff size may be affecting their readings. Users who want a reliable plug-in home monitor with AC adapter — no battery anxiety. Anyone who wants clinically validated accuracy without the complexity of Bluetooth setup and app pairing. Daily monitors who benefit from programmable reminders and automatic last-3 averaging. Users looking for the most affordable way to get a purpose-built extra-large cuff monitor. You may prefer a different monitor if… Your arm circumference is under 16.5 inches — standard Omron monitors like the BP7255, BP7360, or BP7465 cover 9″–17″ with more features. You want Bluetooth syncing and app-based trend tracking — the UA-789AC has no wireless connectivity. See the Omron BP7255 or BP7360. You need multi-user memory — this monitor supports a single user only. The Omron BP7360 and BP7465 offer 2-user memory. You want AFib screening — consider the Omron BP7360 or BP7465.

UA-789AC — Frequently Asked Questions What cuff size does the UA-789AC include? An extra-large upper arm cuff fitting 16.5″ to 23.6″ (42–60 cm) — the largest home blood pressure cuff widely available. Compatible replacement cuffs from A&D include the UA-280A Medium (9.0–14.6″) and UA-281A Large (12.2–17.7″) for household members with smaller arms. Is the UA-789AC clinically validated? Yes. Validated to ANSI/AAMI SP-10 standards with accuracy of ±3 mmHg for pressure and ±5% for pulse rate. It uses oscillometric measurement with A&D's HeartWise™ technology. Does it have Bluetooth or app syncing? No wireless connectivity. You can manually log readings using the free A&D Heart Track App (iOS and Android). If automatic Bluetooth syncing matters, consider the Omron BP7255, BP7360, or BP7465 — though none support cuffs larger than 17 inches. How many readings does it store? 60 readings for a single user with time and date stamps. It also automatically averages your last 3 readings for a more reliable reference number. Does it detect irregular heartbeats? Yes. The irregular heartbeat indicator alerts when an abnormal rhythm is detected during measurement, and it still provides blood pressure and pulse readings. This is not AFib screening — for AFib-specific detection, see the Omron BP7360 or BP7465. What power options does it have? AC adapter (120V) is included in the box for plug-in home use. It also runs on 4 AA batteries (not included) with approximately 120 measurements per set. What warranty does it come with? 5-year warranty on the monitor unit and 2-year warranty on the cuff from A&D Medical. Can I use a smaller cuff with this monitor? Yes. The UA-789AC is compatible with the A&D UA-280A Medium Cuff (9.0–14.6″) and UA-281A Large Cuff (12.2–17.7″), sold separately. This makes it versatile for multi-person households where arm sizes differ. Medical disclaimer: This device is intended for home blood pressure monitoring and informational use only.
