Beurer Upper Arm Blood Pressure Monitor White is designed for households sharing one upper-arm monitor. A fully automatic upper-arm blood pressure monitor with cuff-fit checking, arrhythmia detection and four-user memory. Key verified details include cuff fit: Cuff-fit check for correct positioning; arrhythmia detection: Detects and indicates possible cardiac arrhythmia; and memory: 4 users with 30 stored readings each. This keeps the product focused on the functions Beurer specifies for this model. For everyday ownership, averages: Overall plus 7-day morning and evening averages; risk indicator: Colour-coded risk indicator; and scan & save: Readings can be transferred by smartphone camera to Beurer HealthManager Pro. It also suits users who want stored readings and rolling averages. The BM 27 and BM 26 both offer four-user memory and 7-day averages, but the BM 27's supplied cuff covers 22–42 cm whereas the BM 26's standard cuff is 22–35 cm. That makes it straightforward to assess when these confirmed features are the priority.
