Method
Method	Automatic oscillometric upper-arm measurement during inflation. UK item 10361, EAN 4211125103613; manual model BM 38, technical type BM 48/1. Announced at IFA on 6 September 2024 with planned German availability from October 2024; first actual sale unresolved	Semi-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
Accuracy
Accuracy	Manual display accuracy ±3 mmHg for systolic and diastolic pressure and ±5% for pulse; systolic range 50–280 mmHg, diastolic 30–200 mmHg and pulse 40–199 beats/minute. Maximum cuff pressure 300 mmHg is separate	February 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 validation
Clinical validation	Current manual claims clinical testing to ISO 81060-2. Independent exact-device validation not established in the source pass; headline flag omitted	Nathan 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
Features
Features	Irregular-heartbeat warning, coloured classification scale, cuff-position check and HSD resting indicator. Automatic switch-off after approximately one minute, battery indicator and START/STOP button. No ECG, dedicated AFib screening or voice output	Manual 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

Memory
Memory	Product table says no calculated averages. No reading-recall, user-selection or clock-setting controls established by the complete operating instructions. Website date/time claim and manual's isolated saved-measurement/user paragraphs conflict with the controls; stored memory and user counts left unresolved	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
App
App	Scan & Save photographs the display into beurer HealthManager Pro. No Bluetooth connection from the monitor; smartphone-camera capture is separate from wireless transmission	No Bluetooth, USB or phone-app transfer
Power
Power	Four included 1.5 V LR03 AAA batteries; approximately 300 measurements depending on blood pressure and inflation pressure. USB-C input supports optional 5 V DC / 1 A mains operation, not battery charging. Remove batteries for mains operation; manual lists EU adapter 072.78 and UK adapter 072.79	Two 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
