UA-611 compared with BP N1 Basic

	A&D MedicalUA-611	MicrolifeBP N1 Basic
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	Semi-automatic oscillometric upper-arm measurement. User inflates cuff with pump ball; electronic measurement follows during deflation. Quick-acting valve releases remaining air. No MAM automatic triple mode. 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	Current April 2024 exact guide gives systolic 60–255 and diastolic 40–200 mmHg, pulse 40–199 bpm; global support pulse upper limit is 200. Older MD-V4 English guide gives blood pressure 20–280 mmHg and pulse 40–200. 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the UK BIHS recommendation as manufacturer-declared equivalence to the UA-651 and says the equivalence study is unpublished.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	Current guide claims shared BP 3BTO-A/BIHS technology, while older exact English guide names BP 3BTO-H/ESH. Ukrainian product page claims ISO validation. Medaval reports no peer-reviewed exact N1 Basic validation evidence and bounded STRIDE search recovered none; independent exact validation unresolved, headline validation omitted
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 PAD pulse-arrhythmia indication, not AFib-specific screening or ECG. Hypertension warning, pump-up/air-discharge and low-battery indicators. No date/time controls. Regional page advertises cuff-fit and movement checks; exact guide's labelled display has no separate cuff-fit icon, so feature conflict remains qualified
Cuff
Cuff fits
Cuff fits	22–32 cm	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	Current exact guide explicitly supplies M 22–32 cm cuff, agreeing with Ukrainian maker page's straight M cuff. Optional M-L 22–42 and L 32–42 cm in current guide; L requires black deflation valve. Pump and cuff can use either pneumatic pin; not dual-arm electronic measurement
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	One 30-reading history, oldest overwritten when full. Dedicated memory button recalls older results. Removing batteries clears all saved readings; no timestamps, user selector or automatic averaging. Latest displayed reading can be excluded before storage
App
App	No Bluetooth; readings can be recorded manually	No Bluetooth, USB or PC-transfer function in exact 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	Two 1.5 V AAA alkaline cells, approximately 780 measurements with new batteries. Older exact English guide permits externally charged NiMH. April 2024 guide's technical table additionally lists optional DC 6 V, 600 mA adaptor, but its labelled controls and operating instructions show no mains socket or procedure; this conflict does not establish usable mains support
Design
Display details
Display details	Systolic pressure, diastolic pressure and pulse shown with battery, irregular heartbeat and pressure/classification indicators	LCD showing systolic, diastolic, pulse, PAD, memory number, battery and inflation/deflation indications. ON/OFF and memory buttons, two pneumatic pins. IP20
Size
Size	Approximately 96 × 68 × 130 mm (width × height × depth); approximately 230 g excluding batteries	115 × 59 × 30 mm; 106 g including batteries in current guide and global 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	Current guide establishes monitor, pump ball and supplied M 22–32 cm cuff; complete current regional accessory list not recovered
