Overview
Released––
Measuring
TypeUpper armUpper arm
Clinically validated–Yes
Irregular heartbeat detectionYesYes
AFib detection or ECGNoNo
MethodAutomatic oscillometric upper-arm measurement during inflation; exact BM 81 easyLock item 65511. First on-sale date unconfirmedOscillometric 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
AccuracyMaker display accuracy ±3 mmHg for systolic and diastolic pressure and ±5% for pulse; systolic range 50–250 mmHg, diastolic 30–200 mmHg and pulse 40–180 beats/minute. Cuff-pressure range 0–300 mmHg is not the systolic measuring rangeExact 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 validationMaker claims clinical validation and ESH recognition; Medaval's April 2025 list places this model among monitors with internal or unpublished validation. Independent published exact-device validation not established; headline validation flag omittedSTRIDE 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
FeaturesCuff-fit check, irregular-heartbeat warning, coloured LED risk indicator, date/time and automatic switch-off. No ECG or haemodynamic resting indicator; not a continuous ambulatory monitorGeneric 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 fits24–40 cm–
CuffIntegrated easyLock upper-arm cuff with press-and-turn adjustment for 24–40 cm circumference; no separate tube or hook-and-loop fastenerSupplied 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
Users22
Readings stored120 per user (better)99 per user
Bluetooth and appYesYes
MemoryTwo users with 120 dated readings each; oldest overwritten when full. Averages of all saved readings and morning/evening readings from the latest seven days. All readings saved to a user memory; deletion clears that user's entire memory, without individual-reading deletion or guest modeTwo 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
AppBluetooth Low Energy transfer to beurer HealthManager Pro; can be used without the app. Current instructions specify compatibility with Bluetooth 4.0 smartphones/tablets, not an exact radio-generation claimBluetooth 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
PowerFour 1.5 V AAA LR03 batteries included; approximately 300 measurements depending on blood pressure and inflation pressure. Battery replacement retains readings but requires resetting date/time. ETM's AA battery table conflicts with the exact maker manual and PC-WELT's AAA descriptionFour 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 detailsNon-illuminated LCD with white digits and coloured LED classification indicator; maker display dimensions 3.4 × 7.9 cm. Battery-level and cuff-fit indications; IP22LCD showing pressure, pulse, user, date/time, memory, cuff-fit and Bluetooth indicators. ON/OFF, memory, MAM and user buttons; cuff and DC sockets. IP20
SizeCurrent manual gives 143 × 91 × 22 mm (L × W × H), approximately 280 g with cuff but without batteries. Web table reverses length/width and gives 327 g excluding packaging without the same battery condition138 × 94.5 × 62.5 mm; 402 g including batteries in exact guide and global maker support
In the boxMonitor with integrated 24–40 cm cuff, four AAA LR03 batteries, instructions and quick-start guide; no storage bag. UK product page additionally lists a blood pressure recordExact 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
