Method
Method	Automatic oscillometric measurement with fuzzy-logic-controlled inflation; designed for adult home use; first on-sale date not established	Oscillometric upper-arm monitor. Exact Ukrainian product page identifies IMT/Comfort+ measurement during inflation; June 2023 exact guide instead retains a step describing gradual pressure fall before the result. Maker-page IMT identity retained with that manual conflict explicit. MAM mode takes three measurements with 15-second pauses and displays one analysed result; a questionable reading triggers a fourth. 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	June 2023 guide and Ukrainian maker page publish blood pressure 20–280 mmHg and pulse 40–200 bpm; global support instead lists systolic 60–255 and diastolic 40–200 mmHg. Static pressure accuracy ±3 mmHg and pulse accuracy ±5% in guide. Cuff-pressure display range 0–299 mmHg is separate from measured blood pressure
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the UK BIHS recommendation as manufacturer-declared equivalence to the UA-651 and says the equivalence study is unpublished.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 this exact model for adult home use by accepted equivalence to BP A200 Comfort, whose 2016 studies used ESH-IP 2010 and ANSI/AAMI/ISO 2013. This is not a separate published A3L Comfort trial. Medaval says the equivalence evidence is unpublished and cannot be independently verified against its MDR assessment requirements. Maker claims for pregnancy or other special populations are not established by this adult registry entry
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	Generic irregular-heartbeat indication, cuff-fit and arm-movement indicators, coloured pressure classification scale, low-battery warning and automatic switch-off after approximately one minute. No dedicated AFib algorithm or ECG
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	Ukrainian maker bundle supplies conical soft M-L 22–42 cm cuff. Guide lists M 22–32, M-L 22–42 and L 32–42 cm, with optional pre-shaped cuffs and special connector instructions for optional S 17–22 cm. STRIDE lists validated sizes 17–22, 22–32, 22–42 and 32–52 cm; those are not all supplied
Connections and memory

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	Two user histories with 99 dated readings each, selected by user switch. First recall shows average of all stored readings; guide labels this 28A but does not define a 28-day period. Oldest overwritten when full; selected user's complete history can be cleared, individual saved values cannot. Newly displayed result can be excluded from storage. Readings survive battery replacement but clock requires reset
App
App	No Bluetooth; readings can be recorded manually	USB Mini-B five-pin connection transfers stored readings to Microlife Blood Pressure Analyzer+ PC software. Monitor buttons are disabled during PC connection. No Bluetooth phone connection
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 AA alkaline cells in exact guide and Ukrainian bundle; global support incorrectly lists AAA. Approximately 920 measurements with new batteries, not a separately specified triple-cycle count. Optional Microlife DC 6 V, 600 mA adapter stops battery-current use while connected. NiMH cells supported with external charging
Design
Display details
Display details	Systolic pressure, diastolic pressure and pulse shown with battery, irregular heartbeat and pressure/classification indicators	LCD with date/time, user and MAM indicators; memory, ON/OFF and time buttons. Separate user and single/triple switches, cuff socket, Mini-B USB and DC sockets. IP20
Size
Size	Approximately 96 × 68 × 130 mm (width × height × depth); approximately 230 g excluding batteries	143 × 85 × 58 mm; 385 g including batteries in exact guide and maker pages
