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 65409, EAN 4211125654092; current linked March 2022 manual identifies model BM 35, type BM 35/1. First-sale date unconfirmed	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 60–280 mmHg, diastolic 30–200 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 page displays ESH and German Hypertension Society labels. Medaval lists an ESH self-measurement recommendation for BM 35/1 and a Stride BP derivative claim, but says equivalence to Joytech DBP-1307 has not been demonstrated to MDR requirements. Headline independently established exact-device validation omitted while this evidence remains unresolved	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 Medaval records a specific-population study using a non-standard protocol and unpublished internal DHL data; independent standard-protocol exact-device validation not established, so headline flag omitted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, date/time, application-error message and automatic switch-off. No ECG, dedicated AFib screening, electronic cuff-fit check, 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	22–36 cm	22–42 cm
Cuff
Cuff	Supplied standard cuff 22–36 cm, replacement item 163.537. Optional XL cuff 30–42 cm, item 162.973; headline circumference describes the supplied cuff, not the optional accessory	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

Bluetooth and app
Bluetooth and app	No	Yes
Memory
Memory	Two users with 60 dated readings each; oldest overwritten when full. Averages of all saved readings and morning/evening readings over the latest seven days. The manual's deletion sequence clears the selected user memory despite its misleading individual-deletion heading	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 connection from the monitor. Scan & Save captures the display using a smartphone camera into beurer HealthManager Pro rather than automatically transferring readings	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 alkaline batteries. Exact current manual claims approximately 250 measurements depending on blood pressure and pump pressure, while the current product table says approximately 300. No mains connection established in this exact manual	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 5.5 × 6.0 cm. Physical ON/OFF, memory and setting controls; low-battery and error indicators. Manual IPX0	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	135 × 105 × 53 mm (L × W × H). Current manual approximately 327 g without batteries, without explicitly stating cuff inclusion; product table's 391 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, standard upper-arm cuff, four AAA batteries, storage bag and instructions. Current product page additionally lists a blood pressure record; XL cuff 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
