Method
Method	Automatic oscillometric wrist measurement during deflation. Exact white UK item 65044, EAN 4211125650445; BC 27 dark-grey item 65904 has a separate maker product record. First-sale date unconfirmed	Automatic oscillometric wrist measurement during inflation with Comfort+; exact current European manual identifies BP3KB1-3E. First on-sale date unresolved
Accuracy
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. Current European manual gives systolic 60–255 mmHg, diastolic 40–200 mmHg and pulse 40–199 bpm; older UK manual gives 20–280 mmHg blood pressure and 40–200 bpm. Cuff-pressure display 0–299 mmHg is separate
Clinical validation
Clinical validation	Manual gives an unspecified clinical-test maximum permissible standard deviation of 8 mmHg for systolic and diastolic pressure, without identifying a published study. Medaval reports no peer-reviewed clinical validation information for BC 28; headline independently established validation omitted	STRIDE BP approves equivalence to W2 Slim, whose 2016 adult validation used ESH-IP 2010 and ANSI/AAMI/ISO 2013; not a separate published W3 Comfort trial. STRIDE lists a 13.5–23 cm cuff. Manufacturer BIHS A/A marketing and current manual ESH/ISO wording are retained as claims, not additional independent trials
Features
Features	Irregular-heartbeat warning, coloured classification scale, date/time, application-error messages and automatic switch-off after approximately one minute. No dedicated AFib screening, ECG, movement detection, heart-level position indicator, resting indicator or voice output	Ordinary irregular-heartbeat indication, cuff-fit check, arm-movement warning, single-colour blood-pressure classification scale, low-battery indicator and automatic switch-off after approximately one minute. No dedicated AFib algorithm, MAM sequence or electronic wrist-position sensor established
Cuff
Cuff fits
Cuff fits	14–19.5 cm	–
Cuff
Cuff	Attached wrist cuff for 14–19.5 cm circumference. User must position the cuff at heart level; no electronic position guidance	UK product page and its EN-FR 4119 manual give 13.5–23 cm and a soft D-ring wrist cuff. European August 2026 manual instead gives 13.5–21.5 cm despite the European product page still advertising 23 cm. Headline cuff range omitted pending exact supplied revision confirmation; no inferred second hardware model

Memory
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	Stores 30 readings with date/time and displays average of all stored readings, excluding suboptimal cuff fit; not specifically the last three. Oldest overwritten when full. Readings retained on cell replacement, clock reset. New reading can be excluded; saved history clears together. Exact controls establish no separate user selector
App
App	No Bluetooth or connection from the monitor. Current Scan & Save support captures the displayed values using a smartphone camera into beurer HealthManager Pro; not automatic transfer	–
Power
Power	Two 1.5 V LR03 AAA alkaline batteries; exact manuals claim approximately 170 measurements depending on blood pressure and inflation pressure, while the current product table says approximately 300. Battery operation only	Two 1.5 V AAA alkaline cells; approximately 320 measurements with new cells. NiMH cells supported but must be removed and charged externally
Design
Display details
Display details	Non-illuminated LCD with black digits, maker size 3.5 × 4.0 cm. Physical start/stop and memory controls; low-battery indicator. Manual IP22	LCD with ON/OFF, memory and time controls. Older UK manual gives IP20; current European August 2026 revision gives IP22. Revision conflict retained rather than assuming an upgrade applies to every unit
Size
Size	Exact English and March 2022 multilingual manuals and January 2019 data sheet give 84 × 60 × 29 mm (L × W × H), approximately 92 g with cuff without batteries. Current product table instead gives 60 × 84 × 55 mm and 171 g excluding packaging, with weighing conditions unspecified; differences unresolved	81 × 65 × 21 mm; 112 g including batteries
In the box
In the box	Monitor with attached cuff, two AAA batteries, storage box and instructions. Current product page also lists a blood pressure record. Dedicated English manual's footer is September 2019 despite its download filename using March 2022; newer multilingual manual has the same core specifications	Monitor, storage case, two AAA alkaline batteries, instructions and blood-pressure diary. Current range listing establishes catalogue presence, not worldwide stock or first-sale date
