History

Vaisala's origins date back to the 1930's when Professor Vilho Väisälä, Vaisala's founder and long-time managing director, invented some of the operating principles of a radiosonde. 

From a modest start, the company evolved to become a world leader in many measurement fields. Nowadays Vaisala employs over 1,400 people and exports 98% of its production to over 150 countries. Curiosity, the desire to meet challenges and an extraordinary ability to innovate are at Vaisala's core, both past and present.
