BM 28 compared with BP 3AG1

	BeurerBM 28	MicrolifeBP 3AG1
Overview
Released
Released	–	–
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	Oscillometric upper-arm measurement during deflation. One automatic measurement started with ON/OFF button; no MAM triple-mode selector in exact guide. Actual first retail sale unresolved
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	Exact March 2023 guide gives blood pressure 20–280 mmHg and pulse 40–200 bpm; current global support instead lists systolic 60–255 and diastolic 40–200 mmHg. Static pressure accuracy ±3 mmHg and pulse accuracy ±5%; cuff-pressure display 0–299 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	Exact guide claims shared measurement technology with BP 3BTO-A tested under BIHS protocol. Independent exact BP 3AG1 validation was not recovered in the bounded registry search, so headline validation is omitted. Broad special-population wording in maker guide is not promoted to independently established exact-model validation
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	Generic irregular-heartbeat indication, not AFib-specific screening or ECG recording. Low-battery warning, pulse indicator and automatic switch-off after approximately one minute. No date/time controls or automatic averaging mode in exact guide
Cuff
Cuff fits
Cuff fits	22–42 cm	–
Cuff
Cuff	Supplied universal upper-arm cuff, 22–42 cm circumference	Supplied cuff size not established in recovered global support and guide. Optional S 17–22, M 22–32, M-L 22–42 and L 32–42 cm cuffs and optional pre-shaped cuffs listed; these are not all supplied. Optional small cuff needs the connector from original supplied cuff
Connections and memory
Users
Users	4 (better)	1
Readings stored
Readings stored	30 per user	30
Bluetooth and app
Bluetooth and app	No	No
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	One history of the last 30 readings, with no user selector or timestamps. First recall displays count then latest reading; repeated memory presses show earlier values. Oldest overwritten when full. Complete history can be cleared, individual saved values cannot; newly displayed reading can be excluded
App
App	No Bluetooth; HealthManager Pro Scan & Save uses a smartphone camera to capture the monitor display	No Bluetooth, USB socket or PC-transfer function in exact guide and labelled controls
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	Four 1.5 V AA alkaline cells; approximately 920 measurements with new batteries. Optional Microlife DC 6 V, 600 mA adapter stops battery-current use while connected. NiMH cells supported with external charging, not charged inside monitor
Design
Display details
Display details	Non-illuminated LCD with black digits, 4.6 × 6.1 cm; date/time and battery-level indication	LCD with systolic, diastolic, pulse, irregular-heartbeat, battery and stored-value indications. ON/OFF and memory buttons, cuff and DC sockets. IP20
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	140 × 120 × 70 mm; 400 g including batteries in exact guide and global maker support
In the box
In the box	Monitor, universal cuff, storage bag, blood pressure record and instructions; mains adaptor optional	Exact global supplied-accessory list not recovered; optional cuff sizes and mains adapter are not treated as bundled. Guide filename contains 3AG1-30 and W identifiers while its exact cover and controls identify BP 3AG1; no cosmetic duplicate record created
