Spengler Tensonic blood pressure monitor

Spengler is a historic French medical diagnostics brand founded in 1907 by Emile Spengler and Charles Laubry, famous for inventing the first sphygmomanometer (blood pressure monitor). The brand remains a cornerstone of French medical expertise, particularly in the production of stethoscopes and monitoring equipment.

While the brand's research and development remain deeply rooted in France, most modern electronic models like the Tensonic are manufactured in China to industrial medical standards. Today, Spengler is part of the Spengler Holtex Group, a major European player in the distribution of medical equipment, headquartered in France.
