Method
Method	Automatic oscillometric upper-arm measurement during deflation; BM 28 item 65813, with HSD resting indicator. 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 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	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, HSD haemodynamic resting indicator, irregular-heartbeat warning, classification scale, two alarm times and automatic switch-off; no 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

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 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 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	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

Display details
Display details	Non-illuminated LCD with black digits, 4.6 × 6.1 cm; date/time and battery-level indication	LCD showing systolic, diastolic and pulse readings; single O/I button. 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	68 × 186 × 48.5 mm (width × length × height); 310 g including batteries, excluding cuff in global support table
