Better figure, where one is clearly better
| BeurerBC 21 | MicrolifeBP W90 | |
|---|---|---|
| Overview | ||
| Released | – | – |
| Measuring | ||
| Type | Wrist | Wrist |
| Irregular heartbeat detection | Yes | Yes |
| AFib detection or ECG | No | No |
| Method | Automatic oscillometric wrist measurement during deflation. Exact UK item 65046, EAN 4211125650469; SK2 voice-language version. First-sale date unconfirmed | Automatic oscillometric wrist measurement during deflation; the October 2021 manual describes inflation followed by gradual pressure reduction. First on-sale date unresolved |
| Accuracy | Exact manual display accuracy ±3 mmHg for systolic and diastolic pressure and ±5% for pulse. Systolic range 60–260 mmHg, diastolic 40–199 mmHg and pulse 40–180 beats/minute; cuff-pressure range 0–300 mmHg is separate | Static pressure accuracy ±3 mmHg and pulse ±5% of readout. October 2021 manual gives blood pressure 20–280 mmHg and pulse 40–200 bpm; current support instead lists systolic 60–255 and diastolic 40–200 mmHg. Cuff-pressure display 0–299 mmHg is separate |
| Clinical validation | Exact manual gives an unspecified clinical-test maximum permissible standard deviation of 8 mmHg, without identifying a published study. Medaval reports no peer-reviewed clinical validation information for BC 21, but incorrectly labels its measurement site upper arm; exact maker manual establishes wrist measurement. Independently established headline validation omitted | Maker claims BIHS validation through the measuring technology of BP 3BZ1-3. Medaval reports no published exact-model peer-reviewed validation found; headline validation remains unresolved rather than treating the related-model claim as an exact W90 trial |
| Features | Spoken instructions and results in German, English, French, Italian or Turkish for UK item 65046; three volume levels or off. Shared data sheet separately lists item 65040 with English, Spanish, Polish, Arabic and Farsi; those languages are not part of this UK version. Irregular-heartbeat warning, coloured classification scale, date/time, application-error messages and automatic switch-off. No dedicated AFib screening, ECG, movement detection, heart-level position or resting indicator | Ordinary irregular-heartbeat indication, audible measurement signals, two independently enabled daily reminder alarms, low-battery warning and automatic switch-off after approximately one minute. No dedicated AFib screening or MAM sequence established |
| Cuff | ||
| Cuff fits | 14–19.5 cm | 13.5–21.5 cm |
| Cuff | Attached wrist cuff for 14–19.5 cm circumference. User must position the cuff at heart level; no electronic position guidance | Wrist circumference 13.5–21.5 cm in exact October 2021 manual |
| Connections and memory | ||
| Users | 2 | 2 |
| Readings stored | 60 per user | 99 per user (better) |
| Bluetooth and app | No | No |
| Memory | Two users with 60 dated readings each; oldest overwritten when full. Average of all stored values and morning (05:00–09:00) or evening (18:00–20:00) readings over the latest seven days. Deletion clears the selected user's entire memory | Up to 99 dated readings for each of two user profiles; guest mode does not store readings. Time-button and memory-button sequence selects the user. Oldest reading overwritten when full; stored readings retained after cell replacement, while clock and alarms reset. History can be cleared for the selected user. Instructions establish individual recall, not an automatic average |
| App | No Bluetooth or connection from the monitor. Current Scan & Save support captures displayed values using a smartphone camera into beurer HealthManager Pro; not automatic transfer | – |
| Power | Two 1.5 V LR03 AAA alkaline batteries; approximately 200 measurements depending on blood pressure and inflation pressure. Battery operation only | Two 1.5 V AAA alkaline cells, approximately 460 measurements with new batteries. NiMH cells supported with external charging. Polish product page's table says four AAA cells and DC 6 V, conflicting with its own two-cell package list and the exact manual; copied table is not adopted and no adapter interface is assigned |
| Design | ||
| Display details | Non-illuminated LCD with black digits, maker size 3.8 × 4.5 cm. Physical membrane memory and start/stop controls; low-battery indicator. Manual IP22 | LCD with ON/OFF, memory and time buttons; IP20 in October 2021 manual |
| Size | Exact manual and September 2021 data sheet give 87 × 67 × 31 mm (L × W × H) and approximately 105 g without batteries; data sheet specifies cuff included. Current product table instead gives 87 × 67 × 70 mm and 187 g excluding packaging, with weighing conditions unspecified; differences unresolved | 68 × 68 × 70 mm including cuff in current support; 140 g including batteries |
| In the box | Monitor with attached cuff, two AAA batteries, storage box and instructions. Current product page also lists a blood pressure record | Monitor, storage box, two AAA alkaline batteries and blood-pressure diary listed by Polish maker page. Product resource is Polish; support and operating instructions include English. Photographs show distinct green-front and silver-front maker finishes, without inventing additional hardware configurations |
