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 28 item 65813, with HSD resting indicator. 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 including pregnancy, hypertension and pre-eclampsia, and current manual states ISO 81060-2 testing. Medaval separately identifies BM 28 HSD as lacking its own published validation and requiring proven equivalence to the older validated BM 28; 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 Medaval records a specific-population study using a non-standard protocol and unpublished internal DHL data; independent standard-protocol exact-device validation not established, so headline flag omitted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, HSD haemodynamic resting indicator, irregular-heartbeat warning, classification scale, two alarm times and automatic switch-off; no 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	Supplied universal upper-arm cuff, 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 readings over the latest seven days. Manual defines morning as 05:00–09:00 and evening as 18:00–20:00	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 AA batteries or optional mains adaptor. Current July 2026 manual claims approximately 500 measurements depending on pressure; UK web table and May 2023 datasheet retain approximately 300	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, 4.6 × 6.1 cm; date/time and battery-level indication	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	134 × 103 × 60 mm (L × W × H); current manual approximately 367 g including cuff but excluding batteries. UK page lists 475 g excluding packaging without matching the manual's 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, storage bag, blood pressure record and instructions; mains adaptor 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
