Method
Method	Automatic oscillometric measurement on the upper arm during deflation; first on-sale date not established	Automatic oscillometric upper-arm measurement during deflation; technical model BPHJA2-B, reference BP B1 BT. Gentle+ optimises inflation pressure and deflation speed. First on-sale 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 is distinct from an independent clinical validation result	Static pressure accuracy ±3 mmHg and pulse ±5% of readout; systolic 60–255 mmHg, diastolic 40–200 mmHg and pulse 40–199 beats/minute. Cuff-pressure display 0–299 mmHg is separate
Clinical validation
Clinical validation	Beurer states clinical testing to ISO 81060-2 in the current manual and an ESH validation claim in its datasheet	Exact STRIDE BP listing approves equivalence to BP B3 AFIB, whose adult ISO 81060-2:2018 validation study was published in 2021; cuff 22–42 cm. This is approved equivalence rather than a separate exact-model trial. Manufacturer UK page also cites inherited BIHS A/A claim
Features
Features	Coloured risk scale, irregular heartbeat warning, automatic switch-off and incorrect usage message; no cuff fit check or resting indicator	Ordinary irregular-heartbeat indication, cuff-fit check, arm-movement and cuff-pressure error warnings, three-level reading scale, low-battery indication and automatic switch-off after approximately one minute. No dedicated AFib algorithm or automatic triple-measurement sequence established by exact instructions
Cuff

Cuff
Cuff	Universal upper-arm cuff supplied	Supplied soft non-washable M–L cuff fits 22–42 cm; compatible cuff and connector required. Replacement cuffs must use the supplied matching connector. Spot-clean cuff with damp cloth; no machine or dishwasher washing

Memory
Memory	Average of all saved readings and morning/evening averages for the last seven days; date and time stored	Stores up to 30 readings with date/time and displays their average; oldest overwritten when full. New reading can be excluded, but saved history clears as a whole. Memory erased on battery removal. Manual pairing text refers to user selection 1/2 but exact controls have no user selector or separate per-user capacity; headline user count omitted
App
App	Bluetooth transfer to the free beurer HealthManager Pro app	Bluetooth 5.0 (European manufacturer page), Bluetooth Low Energy (manual), transfers readings to Microlife Connected Health+ on Android/iOS. Wireless transfer starts after measurement or with Bluetooth/time button and switches off after two minutes without a connection. USB-C is a power input, not an established wired data connection
Power
Power	Four 1.5 V LR03 AAA batteries	Four 1.5 V LR3 AAA alkaline batteries, approximately 400 measurements. Rechargeable NiMH cells supported but must be removed and charged externally. Optional USB-C adapter model DSA-5PF21-05, 100–240 V input and 5 V 1 A 5 W output; batteries are not charged by the monitor
