AFib detection or ECG	No	No
Method
Method	Automatic oscillometric upper-arm measurement during inflation; exact UK item 65204. First-sale date unresolved; maker launch notice dated 14 January 2020 does not confirm the first retail day	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 60–255 mmHg, diastolic 40–200 mmHg and pulse 40–199 beats/minute. Cuff-pressure range 0–300 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	Maker datasheet and launch notice claim ESH clinical validation, but Medaval reports no peer-reviewed exact-device validation evidence. Independently established clinical 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 Medaval records a specific-population study using a non-standard protocol and unpublished internal DHL data; independent standard-protocol exact-device validation not established, so headline flag omitted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, cuff-fit check and automatic switch-off. No ECG, dedicated AFib detection, 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	22–42 cm	22–42 cm
Cuff
Cuff	Supplied easyClip universal cuff for 22–42 cm upper-arm circumference, replacement item 164.161. Spring bracket opens for attachment before the hook-and-loop fastener is secured; distinct from easyLock cuff systems	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

Memory
Memory	Two users with 100 dated readings each; oldest overwritten when full. Averages of all stored readings and morning/evening readings over the latest seven days. Holding both function buttons for five seconds deletes the selected user's complete history	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 or radio transfer. Maker Scan & Save feature uses a smartphone camera to read the display into beurer HealthManager Pro; it is not a connection from the monitor	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 LR6 AA alkaline batteries included; manual approximately 500 measurements depending on blood pressure and inflation pressure. Optional 6 V DC / 600 mA mains supply; manual lists EU item 071.95 and UK item 072.05. Batteries are removed 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

Display details
Display details	White illuminated display with black digits, maker 7.4 × 6.4 cm; physical START/STOP, SET, memory and plus/minus buttons. Date/time and low-battery indicator; manual IP22	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	Manual and current web dimensions 138 × 103 × 46 mm (L × W × H); 2021 datasheet instead states 44 mm height. Manual approximately 570 g with cuff and without batteries, datasheet 571 g under the same conditions; current web table's 711 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
