Method
Method	Automatic oscillometric upper-arm measurement during deflation. Exact UK item 60493, EAN 4211125604936; manual model BM 23, technical type BM 25. Range tile and SEO title use BM 25, but active product heading, photos, datasheet and instructions identify BM 23. First-sale date 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. Medaval lists a Stride BP derivative recommendation based on equivalence to BM 28 via Globalcare GCE603, but says unpublished equivalence results cannot be verified to MDR requirements. Independently established exact-device validation remains unresolved; 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, electronic cuff-position check, automatic switch-off and battery indicator. No ECG, dedicated AFib screening, resting indicator 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
Cuff
Cuff fits
Cuff fits	22–42 cm	22–32 cm
Cuff
Cuff	Supplied universal cuff for 22–42 cm upper-arm circumference, replacement item 110.031; conventional hook-and-loop cuff rather than easyClip or easyLock	Supplied M 22–32 cm cuff; optional L 32–42 cm. Single-tube cuff with T-connector attaches at the back of the device

Memory
Memory	No stored reading history, user profiles, date/time or calculated averages established by the product table or complete device operation section. Manual's isolated statement about resetting date/time and retaining saved measurements conflicts with those sections; not treated as an implemented feature	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	No Bluetooth connection from the monitor. Scan & Save captures the display with a smartphone camera into beurer HealthManager Pro rather than automatically transmitting measurements	No Bluetooth, USB or phone-app transfer
Power
Power	Four 1.5 V LR03 AAA batteries included; manual 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 or a demonstrated data connection. Manual lists EU adapter 072.78 and UK adapter 072.79; remove batteries for mains operation	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

Display details
Display details	Non-illuminated LCD with black digits, maker 4.4 × 5.3 cm; physical START/STOP button. Manual IP21	LCD showing systolic, diastolic and pulse readings; single O/I button. IP20
Size
Size	120 × 90 × 40 mm (L × W × H). Manual and datasheet approximately 318 g with cuff and without batteries; current product table's 362 g excluding packaging has unspecified weighing conditions	68 × 186 × 48.5 mm (width × length × height); 310 g including batteries, excluding cuff in global support table
In the box
In the box	Monitor, universal upper-arm cuff, four AAA batteries and instructions according to the datasheet and manual. Product page additionally lists a blood pressure record; mains adapter sold separately	Exact guide establishes monitor with integrated pump and M 22–32 cm cuff; complete regional accessory list unresolved
