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 inflation; exact UK item 65803. July 2014 retail test establishes the sale year; first-sale month unconfirmed
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	Maker 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
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 Medaval lists a Stride BP derivative recommendation based on equivalence to BM 28 via Globalcare GCE603, but says unpublished equivalence results cannot be verified to MDR requirements.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 datasheet claims technical identity with BP3ESH5 and ESH validation. Medaval records a specific-population study using a non-standard protocol and unpublished internal DHL data; independent standard-protocol exact-device validation not established, so headline flag omitted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	Irregular-heartbeat warning, coloured LED classification scale, HSD haemodynamic resting indicator and cuff holder. No ECG or dedicated AFib screening; current UK table says no electronic cuff-fit check
Cuff
Cuff fits
Cuff fits	22–42 cm	22–42 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 maker manual and UK bundle specify 22–42 cm circumference. Technik zu Hause's 2014 tested bundle supplied a 22–36 cm cuff with a separate optional 35–44 cm cuff; current supplied cuff is not inferred from the old review
Connections and memory
Users
Users	–	2
Readings stored
Readings stored	–	60 per user
Bluetooth and app
Bluetooth and app	No	Yes
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	Two users with 60 dated readings each; oldest overwritten when full. Averages of all stored readings and morning/evening readings over the latest seven days. Deletion clears the entire selected user memory; individual readings cannot be deleted
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	Bluetooth Low Energy transfer to beurer HealthManager Pro; USB transfer uses the HealthManager Pro USB uploader and permits app/web viewing. Current manual states compatibility with Bluetooth 4.0 smartphones/tablets; the 2021 datasheet lists Bluetooth 5.0 among supported-device requirements, not an exact monitor radio version
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	Built-in 3.7 V / 400 mAh lithium-ion battery; approximately 50 measurements per charge depending on blood pressure and pump pressure. USB charging from PC or supplied USB mains part; minimum two-hour recharge instruction when depleted. This is rechargeable battery operation, despite the web table's mains-operated label
Design
Display details
Display details	Non-illuminated LCD with black digits, maker 4.4 × 5.3 cm; physical START/STOP button. Manual IP21	Illuminated LCD with black digits, maker 7.0 × 6.5 cm; illuminated sensor touch controls, date/time and battery level. IPX0 according to manual
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	Manual 180 × 99 × 40 mm (L × W × H), approximately 456 g with cuff. Datasheet also gives 456 g but says without batteries despite the built-in cell. Web table gives 51 mm height and 638 g excluding packaging without comparable conditions; retained as source differences
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	Monitor, cuff, cuff holder, USB cable, USB mains part and storage pouch; instructions and quick-start guide available from maker. Regional supplied plug differs; current UK table identifies Euro plug
