Method
Method	Automatic oscillometric upper-arm measurement during deflation. Exact UK item 65409, EAN 4211125654092; current linked March 2022 manual identifies model BM 35, type BM 35/1. First-sale date unconfirmed	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 60–280 mmHg, diastolic 30–200 mmHg and pulse 40–199 beats/minute; cuff-pressure range 0–300 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	Maker page displays ESH and German Hypertension Society labels. Medaval lists an ESH self-measurement recommendation for BM 35/1 and a Stride BP derivative claim, but says equivalence to Joytech DBP-1307 has not been demonstrated to MDR requirements. Headline independently established exact-device validation omitted while this evidence remains unresolved	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, date/time, application-error message and automatic switch-off. No ECG, dedicated AFib screening, electronic cuff-fit check, 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
Cuff	Supplied standard cuff 22–36 cm, replacement item 163.537. Optional XL cuff 30–42 cm, item 162.973; headline circumference describes the supplied cuff, not the optional accessory	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	Two users with 60 dated readings each; oldest overwritten when full. Averages of all saved readings and morning/evening readings over the latest seven days. The manual's deletion sequence clears the selected user memory despite its misleading individual-deletion heading	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 or connection from the monitor. Scan & Save captures the display using a smartphone camera into beurer HealthManager Pro rather than automatically transferring readings	No Bluetooth, USB or phone-app transfer
Power
Power	Four 1.5 V LR03 AAA alkaline batteries. Exact current manual claims approximately 250 measurements depending on blood pressure and pump pressure, while the current product table says approximately 300. No mains connection established in this exact manual	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 5.5 × 6.0 cm. Physical ON/OFF, memory and setting controls; low-battery and error indicators. Manual IPX0	LCD showing systolic, diastolic and pulse readings; single O/I button. IP20
Size
Size	135 × 105 × 53 mm (L × W × H). Current manual approximately 327 g without batteries, without explicitly stating cuff inclusion; product table's 391 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, standard upper-arm cuff, four AAA batteries, storage bag and instructions. Current product page additionally lists a blood pressure record; XL cuff sold separately	Exact guide establishes monitor with integrated pump and M 22–32 cm cuff; complete regional accessory list unresolved
