Overview
Released
Released	–	2014
Measuring
Type
Type	Upper arm	Upper arm
Irregular heartbeat detection
Irregular heartbeat detection	Yes	Yes
AFib detection or ECG
AFib detection or ECG	–	No
Method
Method	Automatic oscillometric measurement on the upper arm during deflation; first on-sale date not established	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	Maker manual specifies display accuracy of ±3 mmHg for systolic and diastolic pressure and ±5% of the displayed pulse value; this is distinct from an independent clinical validation result	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	Beurer states clinical testing to ISO 81060-2 in the current manual and an ESH validation claim in its datasheet	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 Medaval records a specific-population study using a non-standard protocol and unpublished internal DHL data; independent standard-protocol exact-device validation not established, so headline flag omitted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	Coloured risk scale, irregular heartbeat warning, automatic switch-off and incorrect usage message; no cuff fit check or resting indicator	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	22–44 cm	22–42 cm
Cuff
Cuff	Universal upper-arm cuff supplied	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

Memory
Memory	Average of all saved readings and morning/evening averages for the last seven days; date and time stored	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	Bluetooth transfer to the free beurer HealthManager Pro app	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	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, 7.6 × 7.0 cm; illuminated control button	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	13.90 × 9.40 × 4.80 cm (L × W × H)	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, 22–44 cm cuff, four AAA batteries, storage bag, quick guide and blood pressure pass	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
