Measuring
Type
Type	Upper arm	Upper arm
Irregular heartbeat detection
Irregular heartbeat detection	Yes	No
AFib detection or ECG
AFib detection or ECG	–	No
Method
Method	Automatic oscillometric measurement with fuzzy-logic-controlled inflation; designed for adult home use; first on-sale date not established	Fully manual auscultatory upper-arm measurement using the supplied stethoscope and aneroid pressure gauge. Hand inflation and screw-controlled deflation, with readings interpreted by the operator. Actual first retail date unresolved
Accuracy
Accuracy	Maker specification ±3 mmHg pressure and ±5% pulse; pressure range 0–299 mmHg, systolic 60–279 mmHg, diastolic 40–200 mmHg and pulse 40–180 beats/min	March 2021 exact guide gives 0–300 mmHg range and 2 mmHg scale divisions. Static accuracy within ±3 mmHg at 18–33°C and ±6 mmHg at 34–46°C; hysteresis error 0–4 mmHg and air leakage under ±4 mmHg/min. Maker recommends an accuracy test every two years or after mechanical impact
Clinical validation
Clinical validation	A&D UK claims ESH 2010 validation; Medaval identifies the UK BIHS recommendation as manufacturer-declared equivalence to the UA-651 and says the equivalence study is unpublished. The US Validate BP listing covers UA-611 under ANSI/AAMI/ISO 81060-2:2018 with different cuff options; this does not establish direct validation of the supplied UK cuff configuration	Guide cites EN ISO 81060-1 and ANSI/AAMI SP09. These standards are separate from independent clinical validation; exact independent validation unresolved and headline omitted
Features
Features	Irregular heartbeat indicator, pressure progress bar, WHO classification indicator, stored-reading average and automatic power-off; irregular heartbeat indication is not a specific AFib diagnosis	Mechanical dial, separate pump ball and adjustable deflation valve. No automatic pressure or pulse calculation, irregular-heartbeat screening, AFib detection or ECG
Cuff
Cuff fits
Cuff fits	22–32 cm	22–32 cm
Cuff
Cuff	Supplied latex-free and metal-free SlimFit cuff fits 22–32 cm; optional large cuff fits 31–45 cm, sold separately; UK manual says this model is not designed for a small cuff	Supplied soft M 22–32 cm cuff established by exact current guide and Asia-Pacific product page. Other regional bundles are not inferred from retailer variants
Connections and memory

Readings stored	30	–
Bluetooth and app
Bluetooth and app	No	No
Memory
Memory	Last 30 blood pressure and pulse measurements, with stored-reading average; no separate user memories listed	No electronic storage; readings, date and time recorded separately by the operator
App
App	No Bluetooth; readings can be recorded manually	No Bluetooth, USB or phone app
Power
Power	Four AA 1.5 V batteries; maker claims approximately 700 measurements with LR6 alkaline batteries or 200 with R6P manganese batteries at 180 mmHg and 23°C. UA-611 has no DC socket; the optional adapter in the shared manual applies only to UA-651	Mechanical operation without batteries or mains power
Design
Display details
Display details	Systolic pressure, diastolic pressure and pulse shown with battery, irregular heartbeat and pressure/classification indicators	Analogue manometer with pointer; no LCD
Size
Size	Approximately 96 × 68 × 130 mm (width × height × depth); approximately 230 g excluding batteries	Product and support pages list 175 × 70 × 103 mm and 450 g. March 2021 exact guide instead lists 185 × 75 × 110 mm (±1 mm) and weight up to 540 g. Conditions and the reason for the discrepancy are not established
In the box
In the box	UA-611 monitor, 22–32 cm SlimFit cuff, instruction manual and four AA batteries in the UK pack	Current guide lists M cuff, pump ball, valve, stethoscope and soft bag; manometer identified in controls
