Measuring
TypeUpper armUpper arm
Clinically validated–Yes
Irregular heartbeat detectionYesYes
AFib detection or ECG–No
MethodAutomatic oscillometric measurement on the upper arm during deflation; first on-sale date not establishedAutomatic oscillometric upper-arm measurement; HEM-7155T-EBK, distinct from M4 Connect AFib HEM-7196T1-FLE. First on-sale date not established
AccuracyMaker 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 resultMaker's pressure accuracy ±3 mmHg and pulse accuracy ±5% of displayed reading; systolic range 60–260 mmHg, diastolic 40–215 mmHg and pulse 40–180 beats/minute
Clinical validationBeurer states clinical testing to ISO 81060-2 in the current manual and an ESH validation claim in its datasheetMaker manual states an 85-subject investigation under EN ISO 81060-2:2014 and compliance with 2019+A1:2020, plus pregnancy/preeclampsia and type II diabetes validation. Medaval attributes BIHS/STRIDE BP recommendations to equivalence with BP760N HEM-7320-Z, while noting that unpublished equivalence evidence cannot be verified against MDR requirements; these are not published exact-model trials
FeaturesColoured risk scale, irregular heartbeat warning, automatic switch-off and incorrect usage message; no cuff fit check or resting indicatorIrregular-heartbeat, movement, cuff-wrap and high-blood-pressure indicators. Exact manual supports displaying the average of the latest two or three readings within ten minutes despite the web table marking averaging absent. No automatic consecutive three-reading mode, AFib screening or ECG recording
