Specifications

- Type
- Upper arm
- Irregular heartbeat detection
- Yes
- AFib detection or ECG
- No
- Method
- Oscillometric upper-arm measurement during deflation with Gentle+ pressure control. Side switch selects single measurement or MAM mode; three readings with 15-second pauses produce one analysed result. Individual MAM results are not displayed; a fourth is taken if one is questionable. First actual on-sale date unresolved
- Accuracy
- Current 26 June 2025 UK-linked S-V10-1 guide gives systolic 60–255 mmHg, diastolic 40–200 mmHg, pulse 40–199 bpm, static accuracy ±3 mmHg and pulse accuracy ±5%. UK product page instead gives blood pressure 20–280 mmHg and pulse 40–200; global support also gives pulse 40–200. Range differences retained; cuff-pressure display 0–299 mmHg is separate
- Clinical validation
- Maker claims BIHS A/A and shared measurement technology with BP 3BTO-A, but Medaval reports no peer-reviewed validation evidence for exact BP A3 Plus BP 3GX1-5N. Independent exact-model validation remains unresolved, so headline flag is omitted. A3 PC diabetes study is not transferred to this non-PC model
- Features
- Irregular-heartbeat indication, not a dedicated AFib algorithm or ECG. Cuff-fit and arm-movement indicators, coloured classification scale, low-battery warning and automatic switch-off after approximately one minute
Cuff
- Cuff fits
- 22–42 cm
- Cuff
- UK bundle supplies conical soft M-L 22–42 cm cuff. Current guide lists optional S 17–22, M 22–32, L 32–42 and L-XL 32–52 cm sizes and preformed cuffs; these are not all supplied
Connections and memory
- Users
- 2
- Readings stored
- 99 per user
- Bluetooth and app
- No
- Memory
- Two separate histories of 99 dated readings each, selected with user switch. First memory recall displays average of all stored values (current guide labels this 28A without defining a narrower period). Oldest overwritten when full. All stored readings for selected user can be cleared, but not individual stored values; freshly displayed reading can be excluded. History survives battery replacement while clock requires reset
- App
- No Bluetooth, phone app or USB PC-transfer interface in exact guide and current hardware views. Separate A3 PC model has USB; its software support is not transferred
- Power
- Four 1.5 V AA alkaline cells; approximately 920 measurements with new batteries, without a separate triple-cycle count. Optional Microlife DC 6 V, 600 mA adapter stops battery-current use when connected. NiMH cells supported with external charging
Design
- Display details
- LCD with date/time and user indicator, ON/OFF, memory and time buttons, separate user and 1/3 MAM switches. DC adapter socket. IP20
- Size
- 143 × 85 × 58 mm; 368 g including batteries in exact current guide and maker pages
- In the box
- UK maker lists conical soft M-L 22–42 cm cuff, four AA alkaline cells, textile soft bag and blood-pressure diary. Adapter optional. Current guide's isolated wrist-measurement paragraph conflicts with its upper-arm intended use and cuff table and is not copied as device type
Pros and cons
Pros
- Separate memories for two users
- Automatic three-measurement mode
- Supplied 22–42 cm cuff
