Method
Method	Automatic oscillometric wrist measurement during deflation. Exact UK item 65904, EAN 4211125659042. Current page heading and download labels identify BC 27 despite BC 28 in its SEO title and range tile; linked manual identifies type BC 27, technical model BC 28. 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	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	Exact manual states a maximum permissible clinical-test standard deviation of 8 mmHg, but does not identify a published validation study. Medaval reports no peer-reviewed clinical validation information for BC 27; consumer laboratory tests do not establish clinical validation. Headline 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	Fixed wrist cuff for 14–19.5 cm circumference; exact manual requires the supplied attached cuff. Heart-level positioning is a user instruction, not an electronic position sensor	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 readings and seven-day morning (05:00–09:00) or evening (18:00–20:00) averages. Selected user memory can be cleared	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. Scan & Save captures the displayed values using a phone camera into beurer HealthManager Pro; not automatic wireless transfer	–
Power
Power	Two 1.5 V LR03 AAA batteries. Exact linked manual claims approximately 170 measurements depending on blood pressure and inflation pressure; current product table says approximately 300. No mains operation established	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	LCD with black digits; current maker table gives 3.5 × 4.0 cm and claims illumination, while FAZ Kaufkompass's exact tested BC 27 has an unlit display. Illumination remains unresolved rather than assuming a hardware revision. 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 linked manual 84 × 60 × 29 mm (L × W × H), approximately 92 g with cuff without batteries. Current web/data sheet instead gives 60 × 84 × 55 mm and approximately 171 g excluding packaging, without equivalent weighing conditions; conflict 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 and data sheet also list a blood pressure record	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
