Intended for adult home use; first-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	Pressure 30–260 mmHg; pulse 40–199 bpm. Maker accuracy ±3 mmHg pressure and ±5% pulse
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the UK BIHS recommendation as manufacturer-declared equivalence to the UA-651 and says the equivalence study is unpublished.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 product page claims ESH validation and AAMI/ANSI/ISO 81060-2 conformity; older flyer also claims BHS A/A. Exact current hardware revision and independent clinical-study identity unresolved, so headline validation omitted

Maker lists English, Russian, French, Arabic, Persian and Turkish; guide describes language selection and OFF setting. Generic irregular-heartbeat, movement, cuff and hypertension indicators; no AFib-specific screening or ECG
