Measuring
Type
Type	Upper arm	Upper arm
Irregular heartbeat detection
Irregular heartbeat detection	Yes	No
AFib detection or ECG
AFib detection or ECG	No	No
Method
Method	Automatic oscillometric upper-arm measurement during deflation. Exact UK item 60493, EAN 4211125604936; manual model BM 23, technical type BM 25. Range tile and SEO title use BM 25, but active product heading, photos, datasheet and instructions identify BM 23. First-sale date unresolved	Fully manual auscultatory upper-arm measurement using the supplied stethoscope and aneroid gauge. Combined palm dial and pumping ball with adjustable deflation valve; no electronic calculation. Actual first retail date unresolved
Accuracy
Accuracy	Manual display accuracy ±3 mmHg for systolic and diastolic pressure and ±5% for pulse; systolic range 50–280 mmHg, diastolic 30–200 mmHg and pulse 40–199 beats/minute. Maximum cuff pressure 300 mmHg is separate	January 2024 guide gives 0–300 mmHg range, 2 mmHg scale divisions, static accuracy within ±3 mmHg and air leakage under ±4 mmHg/min. Guide has conflicting maintenance wording, at least six-monthly recalibration versus two-year accuracy testing; follow the exact applicable service advice rather than treating these as one interval
Clinical validation
Clinical validation	Current manual claims clinical testing to ISO 81060-2. Medaval lists a Stride BP derivative recommendation based on equivalence to BM 28 via Globalcare GCE603, but says unpublished equivalence results cannot be verified to MDR requirements. Independently established exact-device validation remains unresolved; headline flag omitted	Guide cites EN ISO 81060-1 and ANSI/AAMI SP09. These standards do not establish independent clinical validation; exact independent validation unresolved and headline omitted
Features
Features	Irregular-heartbeat warning, coloured classification scale, electronic cuff-position check, automatic switch-off and battery indicator. No ECG, dedicated AFib screening, resting indicator or voice output	Mechanical palm dial and hand pump with adjustable valve; supplied stethoscope used to hear Korotkoff sounds. No automatic pulse calculation, irregular-heartbeat screening, AFib detection or ECG
Cuff
Cuff fits
Cuff fits	22–42 cm	25.4–40.6 cm
Cuff
Cuff	Supplied universal cuff for 22–42 cm upper-arm circumference, replacement item 110.031; conventional hook-and-loop cuff rather than easyClip or easyLock	Current exact guide specifies supplied 25.4–40.6 cm cuff. Manufacturer product page describes a professional cuff without metal bar and rounds fit to 25–40 cm
Connections and memory
Bluetooth and app
Bluetooth and app	No	No
Memory
Memory	No stored reading history, user profiles, date/time or calculated averages established by the product table or complete device operation section. Manual's isolated statement about resetting date/time and retaining saved measurements conflicts with those sections; not treated as an implemented feature	No electronic storage; readings and date/time recorded separately by the operator
App
App	No Bluetooth connection from the monitor. Scan & Save captures the display with a smartphone camera into beurer HealthManager Pro rather than automatically transmitting measurements	No Bluetooth, USB or phone app
Power
Power	Four 1.5 V LR03 AAA batteries included; manual approximately 300 measurements depending on blood pressure and inflation pressure. USB-C input supports optional 5 V DC / 1 A mains operation, not battery charging or a demonstrated data connection. Manual lists EU adapter 072.78 and UK adapter 072.79; remove batteries for mains operation	Mechanical operation without batteries or mains power
Design
Display details
Display details	Non-illuminated LCD with black digits, maker 4.4 × 5.3 cm; physical START/STOP button. Manual IP21	Analogue manometer with pointer; no LCD
Size
Size	120 × 90 × 40 mm (L × W × H). Manual and datasheet approximately 318 g with cuff and without batteries; current product table's 362 g excluding packaging has unspecified weighing conditions	Global product/support pages list 170 × 65 × 105 mm and 520 g. January 2024 exact guide instead lists 175 × 70 × 103 mm and 500 g; maker does not resolve the discrepancy or separate component weights
In the box
In the box	Monitor, universal upper-arm cuff, four AAA batteries and instructions according to the datasheet and manual. Product page additionally lists a blood pressure record; mains adapter sold separately	Exact guide lists cuff, pump ball, valve, stethoscope and soft bag; manometer is identified in controls
