| BeurerBM 81 easyLock | MicrolifeBP B1 BT | |
|---|---|---|
| Overview | ||
| Released | – | – |
| Measuring | ||
| Type | Upper arm | Upper arm |
| Clinically validated | – | Yes |
| Irregular heartbeat detection | Yes | Yes |
| AFib detection or ECG | No | No |
| Method | Automatic oscillometric upper-arm measurement during inflation; exact BM 81 easyLock item 65511. First on-sale date unconfirmed | Automatic oscillometric upper-arm measurement during deflation; technical model BPHJA2-B, reference BP B1 BT. Gentle+ optimises inflation pressure and deflation speed. First on-sale date unresolved |
| Accuracy | Maker 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 range | Static pressure accuracy ±3 mmHg and pulse ±5% of readout; systolic 60–255 mmHg, diastolic 40–200 mmHg and pulse 40–199 beats/minute. Cuff-pressure display 0–299 mmHg is separate |
| Clinical validation | Maker 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clinical validation and ESH recognition; Medaval's April 2025 list places this model among monitors with internal or unpublished validation.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 omitted | Exact STRIDE BP listing approves equivalence to BP B3 AFIB, whose adult ISO 81060-2:2018 validation study was published in 2021; cuff 22–42 cm. This is approved equivalence rather than a separate exact-model trial. Manufacturer UK page also cites inherited BIHS A/A claim |
| Features | Cuff-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 monitor | Ordinary irregular-heartbeat indication, cuff-fit check, arm-movement and cuff-pressure error warnings, three-level reading scale, low-battery indication and automatic switch-off after approximately one minute. No dedicated AFib algorithm or automatic triple-measurement sequence established by exact instructions |
| Cuff | ||
| Cuff fits | 24–40 cm | 22–42 cm |
| Cuff | Integrated easyLock upper-arm cuff with press-and-turn adjustment for 24–40 cm circumference; no separate tube or hook-and-loop fastener | Supplied soft non-washable M–L cuff fits 22–42 cm; compatible cuff and connector required. Replacement cuffs must use the supplied matching connector. Spot-clean cuff with damp cloth; no machine or dishwasher washing |
| Connections and memory | ||
| Users | 2 | – |
| Readings stored | 120 per user (better) | 30 |
| Bluetooth and app | Yes | Yes |
| Memory | Two 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 mode | Stores up to 30 readings with date/time and displays their average; oldest overwritten when full. New reading can be excluded, but saved history clears as a whole. Memory erased on battery removal. Manual pairing text refers to user selection 1/2 but exact controls have no user selector or separate per-user capacity; headline user count omitted |
| App | Bluetooth 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 claim | Bluetooth 5.0 (European manufacturer page), Bluetooth Low Energy (manual), transfers readings to Microlife Connected Health+ on Android/iOS. Wireless transfer starts after measurement or with Bluetooth/time button and switches off after two minutes without a connection. USB-C is a power input, not an established wired data connection |
| Power | Four 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 description | Four 1.5 V LR3 AAA alkaline batteries, approximately 400 measurements. Rechargeable NiMH cells supported but must be removed and charged externally. Optional USB-C adapter model DSA-5PF21-05, 100–240 V input and 5 V 1 A 5 W output; batteries are not charged by the monitor |
| Design | ||
| Display details | Non-illuminated LCD with white digits and coloured LED classification indicator; maker display dimensions 3.4 × 7.9 cm. Battery-level and cuff-fit indications; IP22 | LCD, ON/OFF, memory and Bluetooth/time controls; IP21 according to current exact manual |
| Size | Current 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 condition | 130 × 93.5 × 52 mm; 240 g including batteries |
| In the box | Monitor 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 record | Monitor, soft 22–42 cm cuff and four AAA batteries listed by UK manufacturer. Mains adapter optional |
