UA-611 compared with BP 3AG1

	A&D MedicalUA-611	MicrolifeBP 3AG1
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. One automatic measurement started with ON/OFF button; no MAM triple-mode selector in exact guide. Actual first retail sale 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	Exact March 2023 guide gives blood pressure 20–280 mmHg and pulse 40–200 bpm; current global support instead lists systolic 60–255 and diastolic 40–200 mmHg. Static pressure accuracy ±3 mmHg and pulse accuracy ±5%; 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the UK BIHS recommendation as manufacturer-declared equivalence to the UA-651 and says the equivalence study is unpublished.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	Exact guide claims shared measurement technology with BP 3BTO-A tested under BIHS protocol. Independent exact BP 3AG1 validation was not recovered in the bounded registry search, so headline validation is omitted. Broad special-population wording in maker guide is not promoted to independently established exact-model 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	Generic irregular-heartbeat indication, not AFib-specific screening or ECG recording. Low-battery warning, pulse indicator and automatic switch-off after approximately one minute. No date/time controls or automatic averaging mode in exact guide
Cuff
Cuff fits
Cuff fits	22–32 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 cuff size not established in recovered global support and guide. Optional S 17–22, M 22–32, M-L 22–42 and L 32–42 cm cuffs and optional pre-shaped cuffs listed; these are not all supplied. Optional small cuff needs the connector from original supplied cuff
Connections and memory

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	One history of the last 30 readings, with no user selector or timestamps. First recall displays count then latest reading; repeated memory presses show earlier values. Oldest overwritten when full. Complete history can be cleared, individual saved values cannot; newly displayed reading can be excluded
App
App	No Bluetooth; readings can be recorded manually	No Bluetooth, USB socket or PC-transfer function in exact guide and labelled controls
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. Optional Microlife DC 6 V, 600 mA adapter stops battery-current use while connected. NiMH cells supported with external charging, not charged inside monitor
Design
Display details
Display details	Systolic pressure, diastolic pressure and pulse shown with battery, irregular heartbeat and pressure/classification indicators	LCD with systolic, diastolic, pulse, irregular-heartbeat, battery and stored-value indications. ON/OFF and memory buttons, cuff and DC sockets. IP20
Size
Size	Approximately 96 × 68 × 130 mm (width × height × depth); approximately 230 g excluding batteries	140 × 120 × 70 mm; 400 g including batteries in exact guide and global maker support
In the box
In the box	UA-611 monitor, 22–32 cm SlimFit cuff, instruction manual and four AA batteries in the UK pack	Exact global supplied-accessory list not recovered; optional cuff sizes and mains adapter are not treated as bundled. Guide filename contains 3AG1-30 and W identifiers while its exact cover and controls identify BP 3AG1; no cosmetic duplicate record created
