Measuring
Type
Type	Upper arm	Upper arm
Clinically validated
Clinically validated	–	Yes
Irregular heartbeat detection
Irregular heartbeat detection	Yes	Yes
Method
Method	Automatic oscillometric measurement with fuzzy-logic-controlled inflation; designed for adult home use; first on-sale date not established	Automatic oscillometric upper-arm measurement during deflation; first on-sale date not established
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	Maker manual specifies static pressure accuracy of ±3 mmHg and pulse accuracy of ±5% of the readout value; distinct from clinical validation
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the UK BIHS recommendation as manufacturer-declared equivalence to the UA-651 and says the equivalence study is unpublished.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	Exact BP B1 Standard appears on STRIDE BP as an approved equivalent to BP B3 AFIB for home use in adults and people with diabetes, with a validated 22–42 cm cuff and a referenced 2021 ISO 81060-2:2018 study
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	Irregular heartbeat indication, cuff fit and movement checks, three-level classification scale, date/time and low-battery indicator

App
App	No Bluetooth; readings can be recorded manually	–
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	Four 1.5 V LR03 AAA batteries or optional DC 5 V, 1 A adaptor through USB-C in the current maker manual; NiMH batteries supported but must be charged externally. USB-C supplies power rather than data transfer
