Method
Method	Automatic oscillometric upper-arm measurement during inflation. UK item 10361, EAN 4211125103613; manual model BM 38, technical type BM 48/1. Announced at IFA on 6 September 2024 with planned German availability from October 2024; first actual sale 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. Independent exact-device validation not established in the source pass; 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 Medaval records a specific-population study using a non-standard protocol and unpublished internal DHL data; independent standard-protocol exact-device validation not established, so headline flag omitted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-position check and HSD resting indicator. Automatic switch-off after approximately one minute, battery indicator and START/STOP button. No ECG, dedicated AFib screening 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 fits	22–42 cm	22–42 cm
Cuff
Cuff	Supplied conventional universal cuff for 22–42 cm upper-arm circumference, replacement item 110.031; no easyClip or easyLock mechanism	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	Product table says no calculated averages. No reading-recall, user-selection or clock-setting controls established by the complete operating instructions. Website date/time claim and manual's isolated saved-measurement/user paragraphs conflict with the controls; stored memory and user counts left unresolved	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	Scan & Save photographs the display into beurer HealthManager Pro. No Bluetooth connection from the monitor; smartphone-camera capture is separate from wireless transmission	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 included 1.5 V LR03 AAA batteries; 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. Remove batteries for mains operation; manual lists EU adapter 072.78 and UK adapter 072.79	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	Non-illuminated LCD with black digits; maker display size 6.2 × 6.2 cm. Manual IP20	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	August 2026 manual 128 × 91 × 46 mm (L × W × H), approximately 357 g with cuff and without batteries. Current website and datasheet give 130 × 91 × 46 mm and approximately 385 g excluding packaging, without defining battery/cuff 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 22–42 cm cuff, four AAA batteries and instructions. Mains adapter sold separately	Monitor, cuff, cuff holder, USB cable, USB mains part and storage pouch; instructions and quick-start guide available from maker.
