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	Semi-automatic oscillometric upper-arm measurement with capacitive pressure sensor. Hand inflation using pump integrated into handle; automatic deflation and digital pressure/pulse results. O/I button interrupts measurement and releases cuff pressure. Actual first retail date 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	February 2024 exact guide gives systolic/diastolic range 20–280 mmHg, pulse 40–200 bpm, 1 mmHg pressure resolution, static pressure accuracy ±3 mmHg and pulse accuracy ±5% of reading
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	Nathan and colleagues, Blood Pressure Monitoring 2015, tested exact Microlife 3AS1-2 in 45 pregnant women including 15 with pre-eclampsia. Overall B/A grade under the British Hypertension Society protocol and passed the study's ISO mean-difference standard; pregnancy-only subgroup A/A. These are study-specific findings, not evidence for every population named in generic maker text
Features
Features	Cuff-fit check, irregular-heartbeat warning, classification scale and automatic switch-off; no HSD resting indicator, AFib screening or ECG	Manual inflation, automatic measurement/deflation, low-battery and inflation indicators. Flashing heart indicates detected pulse, not irregular-heartbeat screening. No AFib detection, ECG or automatic triple-measurement mode
Cuff

Cuff fits	22–42 cm	22–32 cm
Cuff
Cuff	Universal upper-arm cuff for 22–42 cm circumference	Supplied M 22–32 cm cuff; optional L 32–42 cm. Single-tube cuff with T-connector attaches at the back of the device

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 latest measurement retained until the next measurement or battery removal. Hold O/I for at least three seconds to recall. No dated history, user selector or averaging
App
App	No Bluetooth; HealthManager Pro Scan & Save uses a smartphone camera to capture the monitor display	No Bluetooth, USB or phone-app transfer
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	Two 1.5 V AAA alkaline cells; approximately 780 measurements using new batteries. Current guide does not recommend 1.2 V rechargeable cells. Generic guarantee wording about an optional adaptor does not establish a mains socket or mains operation
