BM 58 compared with BP 3AG1

	BeurerBM 58	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; exact UK item 65516. First-sale date unconfirmed. Generic inflation icon on the web page conflicts with its technical table and exact manual operation	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 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	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 datasheet claims ESH clinical validation and 2014/2015 recognition. Medaval lists ESH self-measurement recommendation and DHL manufacturer-declared equivalence, but says exact-device equivalence has not been established to MDR requirements. Independently verified exact-device standard-protocol validation remains unresolved; headline 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	Irregular-heartbeat warning, coloured classification scale, touch-sensor controls, activation/lock switch and cuff holder. No ECG, dedicated AFib detection or haemodynamic resting indicator; current UK table says no electronic cuff-fit check despite a generic feature icon	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	22–30 cm	–
Cuff
Cuff	Supplied upper-arm cuff for 22–30 cm circumference. Separate XL cuff 30–42 cm, maker item 163246; it is an optional accessory rather than the standard headline fit	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	2 (better)	1
Readings stored
Readings stored	60 per user (better)	30
Bluetooth and app
Bluetooth and app	No	No
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. Holding MEM clears all readings in the selected user memory	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	USB transfer to beurer HealthManager PC software or HealthManager Pro USB uploader, with later app/web viewing. No Bluetooth radio; Scan & Save uses a smartphone camera to read the display rather than wireless transfer from the monitor	No Bluetooth, USB socket or PC-transfer function in exact guide and labelled controls
Power
Power	Four 1.5 V LR6 AA alkaline batteries included. Manual claims approximately 500 measurements depending on blood pressure and inflation pressure, while current web table says approximately 250. Optional 6 V DC / 600 mA mains part sold separately; battery and mains are alternative power sources	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	Illuminated black LCD with white digits; maker 8.1 × 12.2 cm. Touch-sensor controls and separate rear activation switch, date/time and battery indicator. IPX0 according to manual	LCD with systolic, diastolic, pulse, irregular-heartbeat, battery and stored-value indications. ON/OFF and memory buttons, cuff and DC sockets. IP20
Size
Size	Manual and datasheet 100 × 150 × 58 mm (L × W × H), approximately 508 g with cuff and without batteries. Web table's 680 g excluding packaging lacks the same weighing conditions	140 × 120 × 70 mm; 400 g including batteries in exact guide and global maker support
In the box
In the box	Monitor, 22–30 cm cuff, USB cable, four AA batteries, storage bag and instructions. UK product page additionally lists a blood pressure record; mains part and XL cuff are separate accessories	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
