Method
Method	Automatic oscillometric upper-arm measurement during inflation. Exact UK item 10350, EAN 4211125103507; manual model BM 48, technical type BM 48/1. Announced at IFA on 6 September 2024 with planned German availability from October 2024; actual first sale unresolved	Oscillometric upper-arm measurement during deflation. Single measurement or MAM automatic triple mode, with 15-second intervals and an additional fourth measurement if one result is questionable. 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	Exact June 2020 guide gives blood pressure 20–280 mmHg and pulse 40–200 bpm; 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 validation for exact current item 10350 not established; headline flag omitted	STRIDE BP lists home use in adults and people with diabetes, with validated 22–42 cm cuff, by approved equivalence to BP B3 AFIB and its 2021 ISO 81060-2 study. This is not a separate B3 BT trial or evidence of AFib screening. Broader special-population claims in maker guide are not promoted to independently verified 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 and low-battery indicator. Single START/STOP button; no ECG, dedicated AFib screening or voice output	Generic irregular-heartbeat indication, not AFib-specific screening or ECG. Cuff-fit, movement and signal checks; pressure classification scale, date/time, pulse and automatic switch-off after approximately one minute
Cuff
Cuff fits
Cuff fits	22–42 cm	–
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 by recovered global support and guide. Optional S 17–22, M 22–32, M-L 22–42, L 32–42 and L-XL 32–52 cm cuffs listed; registry validated cuff size is not proof of the supplied bundle. Washable cover, with bladder removed

Memory
Memory	No calculated averages according to the product table. Complete operation section supplies Bluetooth settings but no on-device recall, user-selection or clock-setting controls. Website date/time claim and isolated saved-measurement/user paragraphs conflict with those controls; memory and user counts unresolved. Reading history is available through the app	Two histories of 99 readings each, with timestamps and oldest overwritten when full. MyBP considers up to four appropriately timed readings per day in the last 28 days, requiring at least 12; separate 28-day average available. Suboptimal cuff-fit readings excluded from these averages. MyCheck compares the latest reading with the stored average. Whole selected user history can be cleared, individual saved values cannot
App
App	Bluetooth transfer to beurer HealthManager Pro; app stores readings and provides export. Automatic transmission can be enabled or disabled using a long press while the monitor is off. Manual publishes 2400–2483 MHz radio band and maximum 5 dBm transmission power, without a Bluetooth version	Bluetooth 4.2 to Microlife Connected Health+. June 2020 guide compatibility is iOS 8 or Android 4.4.2 and later; these are historical guide minimums, not a promise of current app support. Pairing can synchronise date/time. No USB-transfer socket in exact controls
Power
Power	Four included 1.5 V LR03 AAA batteries; approximately 300 measurements depending on blood pressure, inflation pressure and number of Bluetooth connections. Optional USB-C mains input 5 V DC / 1 A; remove batteries for mains use. Not battery charging. Manual 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 adaptor stops battery-current use while connected. NiMH cells require external charging, not charged inside monitor

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 397 g excluding packaging, without defining battery/cuff weighing conditions	138 × 94.5 × 62.5 mm; 402 g including batteries in exact guide and global maker support
In the box
In the box	Monitor, universal 22–42 cm cuff, four AAA batteries and instructions. Mains adapter sold separately	Exact global supplied-accessory list not established; optional cuffs and mains adaptor are not treated as bundled. Guide identifies exact BP B3 BT, distinct from BP B3 AFIB and USB-equipped BP B3 Comfort PC
