Product links

Type: Upper arm
Clinically validated: Yes
Irregular heartbeat detection: Yes
AFib detection or ECG: No
Method: 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: 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: 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: 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

Users: 2
Readings stored: 99 per user
Bluetooth and app: Yes
Memory: 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: 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: 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

Cuff: 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

Display details: 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: 138 × 94.5 × 62.5 mm; 402 g including batteries in exact guide and global maker support
In the box: 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
