Measuring
Type
Type	Upper arm	Upper arm
Clinically validated
Clinically validated	–	Yes
Irregular heartbeat detection
Irregular heartbeat detection	Yes	Yes
AFib detection or ECG
AFib detection or ECG	–	No
Method
Method	Automatic oscillometric measurement on the upper arm during deflation; first on-sale date not established	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	Maker manual specifies display accuracy of ±3 mmHg for systolic and diastolic pressure and ±5% of the displayed pulse value; this is distinct from an independent clinical validation result	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	Beurer states clinical testing to ISO 81060-2 in the current manual and an ESH validation claim in its datasheet	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	Coloured risk scale, irregular heartbeat warning, automatic switch-off and incorrect usage message; no cuff fit check or resting indicator	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	22–44 cm	–
Cuff
Cuff	Universal upper-arm cuff supplied	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
Connections and memory
Users

Readings stored
Readings stored	60 per user	99 per user (better)
Bluetooth and app
Bluetooth and app	Yes	Yes
Memory
Memory	Average of all saved readings and morning/evening averages for the last seven days; date and time stored	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 the free beurer HealthManager Pro app	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 1.5 V LR03 AAA batteries	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
Design
Display details
Display details	Non-illuminated LCD, 7.6 × 7.0 cm; illuminated control button	LCD showing pressure, pulse, user, date/time, memory, cuff-fit and Bluetooth indicators. ON/OFF, memory, MAM and user buttons; cuff and DC sockets. IP20
Size
Size	13.90 × 9.40 × 4.80 cm (L × W × H)	138 × 94.5 × 62.5 mm; 402 g including batteries in exact guide and global maker support
In the box
In the box	Monitor, 22–44 cm cuff, four AAA batteries, storage bag, quick guide and blood pressure pass	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
