A&D MedicalUA-611MicrolifeBP AG1-30
Overview
Released––
Measuring
TypeUpper armUpper arm
Irregular heartbeat detectionYesNo
AFib detection or ECG–No
MethodAutomatic oscillometric measurement with fuzzy-logic-controlled inflation; designed for adult home use; first on-sale date not establishedFully manual auscultatory upper-arm measurement using stethoscope and aneroid gauge. Hand inflation and screw-controlled deflation; readings interpreted by the operator. Current guide specifies trained auscultatory users and adults over 18, at home or in healthcare environments. Actual first retail date unresolved
AccuracyMaker 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/minJune 2025 exact guide gives 0–300 mmHg range, 2 mmHg scale divisions, static accuracy within ±3 mmHg and air leakage under ±4 mmHg/min. Same guide has at-least-six-month recalibration wording and a two-month accuracy-testing interval; these differing maintenance statements are not combined into a single interval
Clinical validationA&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the UK BIHS recommendation as manufacturer-declared equivalence to the UA-651 and says the equivalence study is unpublished.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 configurationCurrent guide cites EN ISO 81060-1 and Class Im compliance with EU Medical Device Regulation. Regulatory compliance is separate from independent clinical validation; exact independent validation unresolved and headline omitted
FeaturesIrregular heartbeat indicator, pressure progress bar, WHO classification indicator, stored-reading average and automatic power-off; irregular heartbeat indication is not a specific AFib diagnosisMechanical dial, pump ball and adjustable deflation valve. Ukrainian maker identifies built-in stethoscope. No automatic pressure or pulse calculation, irregular-heartbeat screening, AFib detection or ECG
Cuff

Design
Display detailsSystolic pressure, diastolic pressure and pulse shown with battery, irregular heartbeat and pressure/classification indicatorsAnalogue manometer with pointer; no LCD
SizeApproximately 96 × 68 × 130 mm (width × height × depth); approximately 230 g excluding batteries175 × 70 × 103 mm and 450 g in global support and Asia-Pacific product page. Current exact guide states weight up to 450 g; component weights not separated
