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; first on-sale date not established
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	Maker manual specifies static pressure accuracy of ±3 mmHg and pulse accuracy of ±5% of the readout value; distinct from clinical validation
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 Medaval records a specific-population study using a non-standard protocol and unpublished internal DHL data; independent standard-protocol exact-device validation not established, so headline flag omitted	Exact BP B4 BT appears on STRIDE BP as an approved equivalent device for home use in adults and people with diabetes, with a validated 22–42 cm cuff; the listing does not identify an underlying direct-study model
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	MAM averages three successive measurements; irregular heartbeat indication, cuff fit and movement checks, classification scale and date/time
Cuff
Cuff fits
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	Soft M–L upper-arm cuff

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	Exact manual and UK page feature heading specify 99 readings per user for two users; a conflicting UK specification bullet says 30 each. Average of all stored readings; oldest reading overwritten when full
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 transfer to Microlife Connected Health+ on Android and iOS
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 LR03 AAA batteries or optional DC 5 V, 1 A adaptor through USB-C; NiMH batteries supported but must be charged externally
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 showing pressure, pulse, user, date/time and stored-reading indicators
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	141 × 94.5 × 56 mm; maker weight 260 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, storage bag, instruction manual and four AAA alkaline batteries
