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. 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	Pressure range 30–260 mmHg and 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 Medaval lists a Stride BP derivative recommendation based on equivalence to BM 28 via Globalcare GCE603, but says unpublished equivalence results cannot be verified to MDR requirements.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 approval. Medaval records equivalence to Rossmax CF175f rather than a published direct Z1 validation study, and notes unpublished equivalence evidence; headline validation omitted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	Cuff-fit and movement detection, hypertension risk indication and generic irregular-heartbeat warning. No AFib-specific screening or ECG
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

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	One history of up to 90 readings with sequence numbers and an average of the last three. No user selector or dated reading history in current guide
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 data transfer; USB-C is a power connector
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. Optional USB-C DC 5 V supply rated at least 1000 mA; guide excludes USB PD chargers and battery charging. Automatic shutdown after one minute without key operation
