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	No
Method
Method	Automatic oscillometric upper-arm measurement during deflation; BM 27 item 65818, distinct from BM 27+ and regional Limited Edition models. First on-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	Maker specifies systolic and diastolic display accuracy ±3 mmHg and pulse ±5%; systolic range 50–280 mmHg, diastolic 30–200 mmHg and pulse 40–199 beats/minute	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 claims clinical validation and ESH recognition, while its datasheet names technical identity to BPM63S. Medaval reports equivalence without published evidence or verifiable MDR compliance, rather than a directly published exact-device validation study; independent validation 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 Medaval records a specific-population study using a non-standard protocol and unpublished internal DHL data; independent standard-protocol exact-device validation not established, so headline flag omitted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	Cuff-fit check, irregular-heartbeat warning, classification scale and automatic switch-off; no HSD resting indicator, AFib screening or ECG	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	Universal upper-arm cuff for 22–42 cm circumference	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
Users	4 (better)	2
Readings stored
Readings stored	30 per user	60 per user (better)
Bluetooth and app
Bluetooth and app	No	Yes
Memory
Memory	Four users with 30 readings each; averages of all saved readings and morning/evening values from the latest 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	No Bluetooth; HealthManager Pro Scan & Save uses a smartphone camera to capture the monitor display	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 LR6 AA batteries included; approximately 700 measurements depending on blood pressure and inflation pressure; no mains adaptor operation for this exact item	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, 5.2 × 3.8 cm; date/time and battery-level indication; IP21	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	112 × 110 × 53 mm (L × W × H); manual and datasheet approximately 341 g including cuff but excluding batteries. Web table's 447 g excludes packaging without matching those 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 cuff, four AA batteries, storage bag, instructions and 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
