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; Gentle+ adaptive pressure and speed control. No confirmed first on-sale date 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	Static pressure accuracy ±3 mmHg, pulse ±5% of readout; systolic range 60–255 mmHg and diastolic 40–200 mmHg. Current manual pulse range 40–199 beats/minute takes precedence over website 40–200; cuff-pressure display range 0–299 mmHg is separate
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the UK BIHS recommendation as manufacturer-declared equivalence to the UA-651 and says the equivalence study is unpublished.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	STRIDE BP lists the exact B1 Classic as an approved equivalent to BP B3 AFIB, whose adult ISO 81060-2:2018 validation was published in 2021; 22–42 cm cuff listed. This is approved equivalence, not a separate B1 Classic trial. Manufacturer's BIHS A/A manual footnote refers to BP 3BTO-A measuring technology
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	Ordinary irregular-heartbeat indication, cuff-fit check, arm-movement and cuff-pressure error indicators, low-battery warning, three-level reading scale and automatic switch-off after approximately one minute. No dedicated AFib algorithm or automatic MAM triple-measurement mode established
Cuff
Cuff fits
Cuff fits	22–32 cm	22–42 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 non-washable soft M–L cuff fits 22–42 cm. Manual also permits M 22–32 cm and optional pre-shaped cuffs, but excludes other Microlife cuff sizes. Spot-clean with damp cloth and soapsuds; no machine or dishwasher washing
Connections and memory
Readings stored
Readings stored	30	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	Stores the last 30 readings with date/time and displays their average; readings with suboptimal cuff fit excluded from the average. Oldest overwritten when full. A new result can be excluded, while stored history clears as a whole rather than individually. All stored readings deleted when batteries are removed; no separate user profiles established
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 AAA alkaline batteries; approximately 400 measurements with new cells. Website calls it rechargeable-battery-friendly, without an internal charging claim. Current manual technical table lists optional DC 6 V 600 mA mains adapter, although its labelled control diagram omits an adapter socket; connection availability therefore needs exact-unit confirmation
Design
Display details
Display details	Systolic pressure, diastolic pressure and pulse shown with battery, irregular heartbeat and pressure/classification indicators	LCD with ON/OFF, memory and time controls; IP20 according to current manual
Size
Size	Approximately 96 × 68 × 130 mm (width × height × depth); approximately 230 g excluding batteries	124 × 92 × 61 mm; 251 g including batteries
In the box
In the box	UA-611 monitor, 22–32 cm SlimFit cuff, instruction manual and four AA batteries in the UK pack	Monitor, 22–42 cm M–L cuff, four AAA alkaline batteries and blood-pressure diary listed by the European product page; instructions available from manufacturer
