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
Method
Method	Automatic oscillometric upper-arm measurement during deflation; first on-sale date not established	Semi-automatic oscillometric upper-arm measurement. User inflates cuff with pump ball; electronic measurement follows during deflation. Quick-acting valve releases remaining air. No MAM automatic triple mode. First retail date unresolved
Accuracy
Accuracy	Maker manual specifies display accuracy of ±3 mmHg for systolic and diastolic pressure and ±5% of the displayed pulse value; this specification is distinct from clinical validation	Current April 2024 exact guide gives systolic 60–255 and diastolic 40–200 mmHg, pulse 40–199 bpm; global support pulse upper limit is 200. Older MD-V4 English guide gives blood pressure 20–280 mmHg and pulse 40–200. Static pressure accuracy ±3 mmHg and pulse accuracy ±5%; cuff-pressure display 0–299 mmHg is separate
Clinical validation
Clinical validation	Beurer states clinical testing to ISO 81060-2 in the manual; exact independent registry confirmation was not established	Current guide claims shared BP 3BTO-A/BIHS technology, while older exact English guide names BP 3BTO-H/ESH. Ukrainian product page claims ISO validation. Medaval reports no peer-reviewed exact N1 Basic validation evidence and bounded STRIDE search recovered none; independent exact validation unresolved, headline validation omitted
Features
Features	Single start/stop button, cuff fit check, irregular heartbeat warning, classification scale and automatic switch-off; maker lists no resting indicator or calculated averages	Generic PAD pulse-arrhythmia indication, not AFib-specific screening or ECG. Hypertension warning, pump-up/air-discharge and low-battery indicators. No date/time controls. Regional page advertises cuff-fit and movement checks; exact guide's labelled display has no separate cuff-fit icon, so feature conflict remains qualified
Cuff
Cuff fits
Cuff fits	22–42 cm	22–32 cm
Cuff
Cuff	Supplied upper-arm cuff	Current exact guide explicitly supplies M 22–32 cm cuff, agreeing with Ukrainian maker page's straight M cuff. Optional M-L 22–42 and L 32–42 cm in current guide; L requires black deflation valve. Pump and cuff can use either pneumatic pin; not dual-arm electronic measurement

Memory
Memory	–	One 30-reading history, oldest overwritten when full. Dedicated memory button recalls older results. Removing batteries clears all saved readings; no timestamps, user selector or automatic averaging. Latest displayed reading can be excluded before storage
App
App	Scan & Save in beurer HealthManager Pro uses a smartphone camera to record the display; no Bluetooth connection	No Bluetooth, USB or PC-transfer function in exact controls
Power
Power	Four 1.5 V LR03 AAA batteries or optional DC 5 V, 1 A mains adaptor through USB-C; USB-C is for mains operation, not charging the disposable batteries	Two 1.5 V AAA alkaline cells, approximately 780 measurements with new batteries. Older exact English guide permits externally charged NiMH. April 2024 guide's technical table additionally lists optional DC 6 V, 600 mA adaptor, but its labelled controls and operating instructions show no mains socket or procedure; this conflict does not establish usable mains support
Design
Display details
Display details	Non-illuminated LCD, 4.4 × 5.3 cm, with black digits; maker lists no date/time display	LCD showing systolic, diastolic, pulse, PAD, memory number, battery and inflation/deflation indications. ON/OFF and memory buttons, two pneumatic pins. IP20
Size
Size	12.00 × 9.00 × 4.00 cm (L × W × H)	115 × 59 × 30 mm; 106 g including batteries in current guide and global support
In the box
In the box	Monitor, 22–42 cm cuff and four AAA batteries	Current guide establishes monitor, pump ball and supplied M 22–32 cm cuff; complete current regional accessory list not recovered
