Our story

In 1931, Professor Vilho Väisälä found a fallen Russian radiosonde. He admired its idea to use radio technology to retrieve observation results but, an innovator at heart, wanted to improve it to his quality standards. 

Väisälä finalized his famous innovation in 1936, founded Vaisala, and sold the first radiosonde pieces to MIT, Massachusetts Institute of Technology. A new global technology pioneer was born. 

Today, Vaisala is a global leader in weather, environmental, and industrial measurements headquartered in Vantaa, Finland. Building on over 80 years of experience, Vaisala strives towards its mission of Observations for a better world. 

We are a reliable partner for customers around the world, offering a comprehensive range of innovative observation and measurement products and services.

Decades of innovation

Vaisala's origins date back to the 1930s when Professor Vilho Väisälä, Vaisala's founder and long-time managing director, invented some of the operating principles of a radiosonde. The company was established in 1936 in Finland, and the first radiosondes were manufactured in the basement of a residential building in the center of Helsinki. From a modest start, the company evolved to become a world leader in many measurement fields. 

Today Vaisala employs over 1,850 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 p​resent.
