Measurements from the A&D TM-2441 are compared to those from the Omron Heartguide BP8000-M (HEM-6410T-ZM) or the BP8000-L (HEM-6410T-ZL), though not in a formal validation.

Validation Publications for Equivalent Devices:

Note: This is a provisional list, as equivalence according to EU Regulation 2017/745 (e.g. MEDDEV 2.7/1 rev 4) is not proven. Accordingly, these publications are not used in the assessment of star-ratings.
