Measuring
Type
Type	Upper arm	Upper arm
Irregular heartbeat detection
Irregular heartbeat detection	Yes	Yes
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	Automatic oscillometric upper-arm measurement during deflation, with semiconductor pressure sensor. Intended for adult home use; first-sale 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	Pressure 30–260 mmHg; pulse 40–199 bpm. Maker accuracy ±3 mmHg pressure and ±5% pulse
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 Medaval lists a Stride BP derivative recommendation based on equivalence to BM 28 via Globalcare GCE603, but says unpublished equivalence results cannot be verified to MDR requirements.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	Maker claims ESH validation and AAMI/ANSI/ISO 81060-2 conformity. Exact current hardware revision and independent clinical-study identity unresolved, so headline validation 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	Generic irregular-heartbeat, movement and hypertension indicators; one-touch automatic operation. No AFib-specific screening, ECG or speech guidance documented
Cuff
Cuff fits
Cuff fits	22–42 cm	24–40 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	Latex-free Universal Cone Cuff, 24–40 cm; flyer says other cuff sizes available upon request but does not specify their ranges

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	Single 90-reading history with latest-three average and sequence numbers; no separate user histories, guest mode or clock documented
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 or phone-app transfer documented
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	Four AAA cells, DC 6 V; automatic shutdown after one minute without key operation. Exact model guide has no AC-power specification and product page lists no adaptor socket

Display details
Display details	Non-illuminated LCD with black digits, maker 4.4 × 5.3 cm; physical START/STOP button. Manual IP21	LCD with movement, irregular-heartbeat, memory, pressure, pulse and risk indicators; IP21
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	124 × 85 × 68.6 mm (L × W × H); maker guide lists 330 g without batteries
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	Maker lists batteries, Universal Cone Cuff, instruction manual and string bag
