Measuring
Type
Type	Upper arm	Upper arm
Irregular heartbeat detection
Irregular heartbeat detection	Yes	Yes
AFib detection or ECG
AFib detection or ECG	No	No
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	Oscillometric upper-arm measurement during deflation. One automatic measurement started with ON/OFF button; no MAM triple-mode selector in exact guide. Actual first retail sale 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	Exact March 2023 guide gives blood pressure 20–280 mmHg and pulse 40–200 bpm; current global support instead lists systolic 60–255 and diastolic 40–200 mmHg. Static pressure accuracy ±3 mmHg and pulse accuracy ±5%; cuff-pressure display 0–299 mmHg is separate
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	Exact guide claims shared measurement technology with BP 3BTO-A tested under BIHS protocol. Independent exact BP 3AG1 validation was not recovered in the bounded registry search, so headline validation is omitted. Broad special-population wording in maker guide is not promoted to independently established exact-model validation
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	Generic irregular-heartbeat indication, not AFib-specific screening or ECG recording. Low-battery warning, pulse indicator and automatic switch-off after approximately one minute. No date/time controls or automatic averaging mode in exact guide
Cuff

Cuff
Cuff	Supplied conventional universal cuff for 22–42 cm upper-arm circumference, replacement item 110.031; no easyClip or easyLock mechanism	Supplied cuff size not established in recovered global support and guide. Optional S 17–22, M 22–32, M-L 22–42 and L 32–42 cm cuffs and optional pre-shaped cuffs listed; these are not all supplied. Optional small cuff needs the connector from original supplied cuff

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 history of the last 30 readings, with no user selector or timestamps. First recall displays count then latest reading; repeated memory presses show earlier values. Oldest overwritten when full. Complete history can be cleared, individual saved values cannot; newly displayed reading can be excluded
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 socket or PC-transfer function in exact guide and labelled controls
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	Four 1.5 V AA alkaline cells; approximately 920 measurements with new batteries. Optional Microlife DC 6 V, 600 mA adapter stops battery-current use while connected. NiMH cells supported with external charging, not charged inside monitor

Display details
Display details	Non-illuminated LCD with black digits; maker display size 6.2 × 6.2 cm. Manual IP20	LCD with systolic, diastolic, pulse, irregular-heartbeat, battery and stored-value indications. ON/OFF and memory buttons, cuff and DC sockets. IP20
Size
Size	August 2026 manual 128 × 91 × 46 mm (L × W × H), approximately 357 g with cuff and without batteries. Current website and datasheet give 130 × 91 × 46 mm and approximately 385 g excluding packaging, without defining battery/cuff weighing conditions	140 × 120 × 70 mm; 400 g including batteries in exact guide and global maker support
