UA-611 compared with BP A3 Plus

	A&D MedicalUA-611	MicrolifeBP A3 Plus
Overview
Released
Released	–	–
Measuring
Type
Type	Upper arm	Upper arm
Irregular heartbeat detection
Irregular heartbeat detection	Yes	Yes
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	Oscillometric upper-arm measurement during deflation with Gentle+ pressure control. Side switch selects single measurement or MAM mode; three readings with 15-second pauses produce one analysed result. Individual MAM results are not displayed; a fourth is taken if one is questionable. First actual 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	Current 26 June 2025 UK-linked S-V10-1 guide gives systolic 60–255 mmHg, diastolic 40–200 mmHg, pulse 40–199 bpm, static accuracy ±3 mmHg and pulse accuracy ±5%. UK product page instead gives blood pressure 20–280 mmHg and pulse 40–200; global support also gives pulse 40–200. Range differences retained; 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the UK BIHS recommendation as manufacturer-declared equivalence to the UA-651 and says the equivalence study is unpublished.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	Maker claims BIHS A/A and shared measurement technology with BP 3BTO-A, but Medaval reports no peer-reviewed validation evidence for exact BP A3 Plus BP 3GX1-5N. Independent exact-model validation remains unresolved, so headline flag is omitted. A3 PC diabetes study is not transferred to this non-PC model
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, not a dedicated AFib algorithm or ECG. Cuff-fit and arm-movement indicators, coloured classification scale, low-battery warning and automatic switch-off after approximately one minute
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	UK bundle supplies conical soft M-L 22–42 cm cuff. Current guide lists optional S 17–22, M 22–32, L 32–42 and L-XL 32–52 cm sizes and preformed cuffs; these are not all supplied
Connections and memory
Users

Readings stored
Readings stored	30	99 per user (better)
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 separate histories of 99 dated readings each, selected with user switch. First memory recall displays average of all stored values (current guide labels this 28A without defining a narrower period). Oldest overwritten when full. All stored readings for selected user can be cleared, but not individual stored values; freshly displayed reading can be excluded. History survives battery replacement while clock requires reset
App
App	No Bluetooth; readings can be recorded manually	No Bluetooth, phone app or USB PC-transfer interface in exact guide and current hardware views. Separate A3 PC model has USB; its software support is not transferred
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; approximately 920 measurements with new batteries, without a separate triple-cycle count. Optional Microlife DC 6 V, 600 mA adapter stops battery-current use when 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 and user indicator, ON/OFF, memory and time buttons, separate user and 1/3 MAM switches. DC adapter socket. IP20
Size
Size	Approximately 96 × 68 × 130 mm (width × height × depth); approximately 230 g excluding batteries	143 × 85 × 58 mm; 368 g including batteries in exact current guide and maker pages
In the box
In the box	UA-611 monitor, 22–32 cm SlimFit cuff, instruction manual and four AA batteries in the UK pack	UK maker lists conical soft M-L 22–42 cm cuff, four AA alkaline cells, textile soft bag and blood-pressure diary. Adapter optional. Current guide's isolated wrist-measurement paragraph conflicts with its upper-arm intended use and cuff table and is not copied as device type
