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 pressure gauge. Hand inflation and screw-controlled deflation, with readings interpreted by the operator. 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	March 2021 exact guide gives 0–300 mmHg range and 2 mmHg scale divisions. Static accuracy within ±3 mmHg at 18–33°C and ±6 mmHg at 34–46°C; hysteresis error 0–4 mmHg and air leakage under ±4 mmHg/min. Maker recommends an accuracy test every two years or after mechanical impact
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 Medaval lists a Stride BP derivative recommendation based on equivalence to BM 28 via Globalcare GCE603, but says unpublished equivalence results cannot be verified to MDR requirements.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 are separate from 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 dial, separate pump ball and adjustable deflation valve. No automatic pressure or pulse calculation, irregular-heartbeat screening, AFib detection or ECG
Cuff
Cuff fits
Cuff fits	22–42 cm	22–32 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	Supplied soft M 22–32 cm cuff established by exact current guide and Asia-Pacific product page. Other regional bundles are not inferred from retailer variants
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, date and 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	Product and support pages list 175 × 70 × 103 mm and 450 g. March 2021 exact guide instead lists 185 × 75 × 110 mm (±1 mm) and weight up to 540 g. Conditions and the reason for the discrepancy are not established
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	Current guide lists M cuff, pump ball, valve, stethoscope and soft bag; manometer identified in controls
