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, marketed as Gentle+ pressure and speed control. Exact operation describes pumping followed by gradual pressure reduction; no MAM sequence established despite copied MAM-button wording in some instructions. First on-sale 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	July 2025 E-V10 manual gives systolic 60–255 mmHg, diastolic 40–200 mmHg and pulse 40–199 bpm; static pressure ±3 mmHg and pulse ±5%. UK product/support instead give blood pressure 20–280 mmHg and pulse 40–200 bpm; September 2023 S-V11 manual says pulse 20–200 despite its error table's 40 bpm threshold. Conflicting ranges qualified; cuff-pressure display 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the UK BIHS recommendation as manufacturer-declared equivalence to the UA-651 and says the equivalence study is unpublished.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 A2 Basic as an equivalent device to BP A100, for adults and diabetes with 22–42 and 32–52 cm cuffs. Headline indicates registry acceptance by equivalence, not a separate exact-model trial. Maker manual instead cites BP 3BT0-A technology; Medaval notes that the equivalence evidence does not establish MDR-compliant accuracy validation
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 IHB indication, traffic-light classification, cuff check, movement warning, low-battery indicator and automatic switch-off after approximately one minute. No dedicated AFib screening or app
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 conical M-L cuff fits 22–42 cm in UK maker product page. Manual lists optional S 17–22, M 22–32, L 32–42 and L-XL 32–52 cm; do not treat all optional sizes as supplied
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 last 30 dated readings and first displays their average on recall, then individual results. Oldest overwritten when full. History retained on cell replacement while clock resets. Newly displayed reading can be excluded; stored history clears together. No user-selector operation established; manuals contain copied two-user wording, so headline user count remains omitted
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 AA alkaline batteries, approximately 920 measurements with new cells in July 2025 manual. Optional Microlife DC 6 V, 600 mA mains adapter uses dedicated socket without drawing battery current. NiMH rechargeable cells supported but charged externally; no internal charging
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, cuff socket and adapter socket; IP20 in July 2025 manual
Size
Size	Approximately 96 × 68 × 130 mm (width × height × depth); approximately 230 g excluding batteries	UK product/support and July 2025 E-V10 manual agree on 135.5 × 82 × 57 mm and 340 g including batteries. September 2023 S-V11 instead says 157.5 × 105 × 61.5 mm and 415 g; those conflicting older figures are not assigned to the headline
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, textile storage pouch, four AA alkaline cells, blood-pressure diary and M-L 22–42 cm cuff listed by UK maker page; mains adapter optional
