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 inflation. UK item 65400, EAN 4211125654009; manual type BM 64. Announced on 12 November 2023 with planned German availability from March 2024; actual first-sale date 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 validation for this exact model not established. The shared launch release's pregnancy-validation claim belongs to BM 53, not BM 64	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 Medaval records a specific-population study using a non-standard protocol and unpublished internal DHL data; independent standard-protocol exact-device validation not established, so headline flag omitted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 detection flags possible atrial fibrillation, without recording an ECG. Coloured classification scale, cuff-position check, HSD resting indicator and low-battery indication. Maker retains triple-measurement mode; May 2024 instructions describe three measurements with 30-second waits and a final average, while September 2026 instructions omit that operation section	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 premium cuff fits upper-arm circumferences of 22–42 cm; conventional tube connection, not easyClip or easyLock	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 separately selected users with 120 readings each; oldest reading replaced when full. Recall individual readings and average of all stored readings, plus morning (05:00–09:00) and evening (18:00–20:00) averages over the last seven days. Date/time and user-selection slider explicitly described in the manual	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 beurer HealthManager Pro with automatic transfer configurable on the monitor; six-digit pairing PIN. Manual publishes 2400–2483 MHz band and maximum 5 dBm transmission power, without a Bluetooth version	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 LR6 AA batteries; approximately 300 measurements depending on blood pressure, inflation pressure and Bluetooth connections. Optional USB-C mains supply 5 V DC / 1 A; remove batteries for mains use. Included USB-C cable does not charge 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	Illuminated inverse XL LCD with white digits on black; four sensor touch buttons and a central START/STOP control. 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	143 × 105 × 60 mm (L × W × H). Manual and datasheet approximately 450 g with cuff and without batteries; current UK website lists 646 g excluding packaging without specifying cuff/battery 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, 22–42 cm premium cuff, four AA batteries, USB-C cable, storage pouch and instructions; mains adapter optional	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
