Measuring
Type
Type	Upper arm	Upper arm
Irregular heartbeat detection

AFib detection or ECG
AFib detection or ECG	Yes	Yes
Method
Method	Automatic oscillometric upper-arm measurement during inflation. UK item 65400, EAN 4211125654009; manual type BM 64. Announced on 12 November 2023 with planned German availability from March 2024; actual first-sale date unresolved	Automatic oscillometric upper-arm measurement during deflation with semiconductor pressure sensor. First-sale date unresolved
Accuracy
Accuracy	Manual display accuracy ±3 mmHg for systolic and diastolic pressure and ±5% for pulse. Systolic range 50–280 mmHg, diastolic 30–200 mmHg and pulse 40–199 beats/minute; maximum cuff pressure 300 mmHg is separate	Pressure 30–260 mmHg; pulse 40–199 bpm. Maker accuracy ±3 mmHg pressure and ±5% pulse
Clinical validation
Clinical validation	Current manual claims clinical testing to ISO 81060-2; independent validation for this exact model not established. The shared launch release's pregnancy-validation claim belongs to BM 53, not BM 64	STRIDE BP lists Z5 as equivalent to the validated Rossmax CF175, rather than directly studied. Medaval says the equivalence evidence is unpublished and cannot be checked against MDR requirements; headline validation omitted
Features
Features	Advanced arrhythmia detection flags possible atrial fibrillation, without recording an ECG. Coloured classification scale, cuff-position check, HSD resting indicator and low-battery indication. Maker retains triple-measurement mode; May 2024 instructions describe three measurements with 30-second waits and a final average, while September 2026 instructions omit that operation section	PARR flags AFib, premature contractions and combined findings; not an ECG. Cuff-fit, movement and hypertension indicators; non-storing guest mode. Generic tachycardia/bradycardia marketing does not establish dedicated detection icons

Memory
Memory	Two separately selected users with 120 readings each; oldest reading replaced when full. Recall individual readings and average of all stored readings, plus morning (05:00–09:00) and evening (18:00–20:00) averages over the last seven days. Date/time and user-selection slider explicitly described in the manual	Two 60-reading histories with date/time; latest-three average and seven-day morning/nighttime averages. Morning uses 04:00–11:59 and nighttime 18:00–02:00. Oldest reading replaced when full; guest readings not stored
App
App	Bluetooth transfer to beurer HealthManager Pro with automatic transfer configurable on the monitor; six-digit pairing PIN. Manual publishes 2400–2483 MHz band and maximum 5 dBm transmission power, without a Bluetooth version	Bluetooth low energy transfers new and saved readings to the phone app after pairing. USB cable is specified for power only; a generic BP Manager diagram does not establish PC data transfer
Power
Power	Four included 1.5 V LR6 AA batteries; approximately 300 measurements depending on blood pressure, inflation pressure and Bluetooth connections. Optional USB-C mains supply 5 V DC / 1 A; remove batteries for mains use. Included USB-C cable does not charge batteries	Built-in non-detachable DC 3.7 V lithium-ion battery; Type-C input 5 V, 1 A. Maker claims approximately 600 measurements per full charge, depending on battery and storage condition; charging takes up to three hours depending on discharge. Green charging light goes out when full. Battery replacement by authorised service centre; automatic shutdown after one minute
