Overview
Released––
Measuring
TypeUpper armUpper arm
Clinically validated–Yes
Irregular heartbeat detectionYesNo
AFib detection or ECG–No
MethodAutomatic oscillometric upper-arm measurement during deflation; first on-sale date not establishedSemi-automatic oscillometric upper-arm measurement with capacitive pressure sensor. Hand inflation using pump integrated into handle; automatic deflation and digital pressure/pulse results. O/I button interrupts measurement and releases cuff pressure. Actual first retail date unresolved
AccuracyMaker manual specifies display accuracy of ±3 mmHg for systolic and diastolic pressure and ±5% of the displayed pulse value; this specification is distinct from clinical validationFebruary 2024 exact guide gives systolic/diastolic range 20–280 mmHg, pulse 40–200 bpm, 1 mmHg pressure resolution, static pressure accuracy ±3 mmHg and pulse accuracy ±5% of reading
Clinical validationBeurer states clinical testing to ISO 81060-2 in the manual; exact independent registry confirmation was not establishedNathan and colleagues, Blood Pressure Monitoring 2015, tested exact Microlife 3AS1-2 in 45 pregnant women including 15 with pre-eclampsia. Overall B/A grade under the British Hypertension Society protocol and passed the study's ISO mean-difference standard; pregnancy-only subgroup A/A. These are study-specific findings, not evidence for every population named in generic maker text
FeaturesSingle start/stop button, cuff fit check, irregular heartbeat warning, classification scale and automatic switch-off; maker lists no resting indicator or calculated averagesManual inflation, automatic measurement/deflation, low-battery and inflation indicators. Flashing heart indicates detected pulse, not irregular-heartbeat screening. No AFib detection, ECG or automatic triple-measurement mode

Bluetooth and appNoNo
Memory–One latest measurement retained until the next measurement or battery removal. Hold O/I for at least three seconds to recall. No dated history, user selector or averaging
AppScan & Save in beurer HealthManager Pro uses a smartphone camera to record the display; no Bluetooth connectionNo Bluetooth, USB or phone-app transfer
PowerFour 1.5 V LR03 AAA batteries or optional DC 5 V, 1 A mains adaptor through USB-C; USB-C is for mains operation, not charging the disposable batteriesTwo 1.5 V AAA alkaline cells; approximately 780 measurements using new batteries. Current guide does not recommend 1.2 V rechargeable cells. Generic guarantee wording about an optional adaptor does not establish a mains socket or mains operation
