Method
Method	Automatic oscillometric upper-arm measurement during inflation; exact UK item 65803. July 2014 retail test establishes the sale year; first-sale month unconfirmed	Automatic oscillometric upper-arm measurement during deflation; technical model BPHJA2-B, reference BP B1 BT. Gentle+ optimises inflation pressure and deflation speed. First on-sale date unresolved
Accuracy
Accuracy	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	Static pressure accuracy ±3 mmHg and pulse ±5% of readout; systolic 60–255 mmHg, diastolic 40–200 mmHg and pulse 40–199 beats/minute. Cuff-pressure display 0–299 mmHg is separate
Clinical validation
Clinical validation	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 Medaval records a specific-population study using a non-standard protocol and unpublished internal DHL data; independent standard-protocol exact-device validation not established, so headline flag omitted	Exact STRIDE BP listing approves equivalence to BP B3 AFIB, whose adult ISO 81060-2:2018 validation study was published in 2021; cuff 22–42 cm. This is approved equivalence rather than a separate exact-model trial. Manufacturer UK page also cites inherited BIHS A/A claim
Features
Features	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	Ordinary irregular-heartbeat indication, cuff-fit check, arm-movement and cuff-pressure error warnings, three-level reading scale, low-battery indication and automatic switch-off after approximately one minute. No dedicated AFib algorithm or automatic triple-measurement sequence established by exact instructions
Cuff

Cuff fits	22–42 cm	22–42 cm
Cuff
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	Supplied soft non-washable M–L cuff fits 22–42 cm; compatible cuff and connector required. Replacement cuffs must use the supplied matching connector. Spot-clean cuff with damp cloth; no machine or dishwasher washing
Connections and memory

Readings stored	60 per user (better)	30
Bluetooth and app
Bluetooth and app	Yes	Yes
Memory
Memory	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	Stores up to 30 readings with date/time and displays their average; oldest overwritten when full. New reading can be excluded, but saved history clears as a whole. Memory erased on battery removal. Manual pairing text refers to user selection 1/2 but exact controls have no user selector or separate per-user capacity; headline user count omitted
App
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	Bluetooth 5.0 (European manufacturer page), Bluetooth Low Energy (manual), transfers readings to Microlife Connected Health+ on Android/iOS. Wireless transfer starts after measurement or with Bluetooth/time button and switches off after two minutes without a connection. USB-C is a power input, not an established wired data connection
Power
Power	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	Four 1.5 V LR3 AAA alkaline batteries, approximately 400 measurements. Rechargeable NiMH cells supported but must be removed and charged externally. Optional USB-C adapter model DSA-5PF21-05, 100–240 V input and 5 V 1 A 5 W output; batteries are not charged by the monitor
Design
Display details
Display details	Illuminated LCD with black digits, maker 7.0 × 6.5 cm; illuminated sensor touch controls, date/time and battery level. IPX0 according to manual	LCD, ON/OFF, memory and Bluetooth/time controls; IP21 according to current exact manual
Size
Size	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	130 × 93.5 × 52 mm; 240 g including batteries
In the box
In the box	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	Monitor, soft 22–42 cm cuff and four AAA batteries listed by UK manufacturer. Mains adapter optional
