	BeurerBM 27	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 27 item 65818, distinct from BM 27+ and regional Limited Edition models. 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 and ESH recognition, while its datasheet names technical identity to BPM63S. Medaval reports equivalence without published evidence or verifiable MDR compliance, rather than a directly published exact-device validation study; 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, irregular-heartbeat warning, classification scale and automatic switch-off; no HSD resting indicator, 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	Universal upper-arm cuff for 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 values from the latest seven days	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 LR6 AA batteries included; approximately 700 measurements depending on blood pressure and inflation pressure; no mains adaptor operation for this exact item	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, 5.2 × 3.8 cm; date/time and battery-level indication; IP21	LCD with systolic, diastolic, pulse, irregular-heartbeat, battery and stored-value indications. ON/OFF and memory buttons, cuff and DC sockets. IP20
Size
Size	112 × 110 × 53 mm (L × W × H); manual and datasheet approximately 341 g including cuff but excluding batteries. Web table's 447 g excludes packaging without matching those 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, four AA batteries, storage bag, instructions and blood pressure record	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
