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	Yes	No
Method
Method	Automatic oscillometric upper-arm measurement 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 specification is distinct from clinical validation	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 and suitability during pregnancy; exact independent registry confirmation was not established	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 Medaval records a specific-population study using a non-standard protocol and unpublished internal DHL data; independent standard-protocol exact-device validation not established, so headline flag omitted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	Advanced arrhythmia indication including possible atrial fibrillation, automatic triple measurement, resting indicator, cuff fit check, classification scale and automatic switch-off	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 upper-arm cuff	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

Readings stored
Readings stored	100 per user (better)	60 per user
Bluetooth and app
Bluetooth and app	No	Yes
Memory
Memory	100 readings per user; average of all saved readings and morning/evening readings from the last seven days	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 in beurer HealthManager Pro uses a smartphone camera to record the display; no Bluetooth connection	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 AAA batteries or optional DC 5 V, 1 A mains adaptor; maker claims approximately 300 measurements depending on pressure	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	Illuminated LCD, 8.0 × 7.4 cm, with black digits on a white background	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	14.00 × 9.40 × 4.60 cm (L × W × H), current maker product page	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, 22–42 cm cuff, four AAA batteries and storage bag; maker product page also lists a blood pressure record	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
