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.

Reliable Customer Experience Requires Constant Attention:

Customer feedback is very important for us, and we appreciate the time and effort customers take when giving their view on our performance. Analyzing how we have succeeded compared to the expectations allows us to investigate gaps and develop our operations.

We invite customers and other stakeholders to give feedback in several different ways: We provide short and to-the-point surveys e.g. after service cases, deliveries and training sessions. Additionally, we conduct an annual customer satisfaction survey comprising of telephone interviews with key customer contacts from around the world.

The customer satisfaction survey results steer our improvement efforts across our entire operation. We want to align our internal measures with what customers expect from Vaisala. When we focus on the areas that matter most to our customers, we can continue to deliver the quality that our customers expect.

Annual Customer Satisfaction Survey 2016:

In 2016, over 600 customers and representatives participated in a telephone survey conducted by an independent agency. According to the results, we are on the right track in improving delivery performance, responsiveness, quality, calibration and repair turnaround times as well as problem handling, and we want to continue these efforts.

Vaisala's Origins

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. 

Nowadays Vaisala employs approximately 1,600 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.
