Our technology and expertise help our customers optimize production processes and maintain the highest level of product quality.

We look forward to working with you to develop innovative sensor solutions to meet your needs. Do not hesitate to contact us to learn more about our services and products.


In 1975 our company was founded by Mr. Kurt Künzli. The foundation was based on a very special occasion: the new development of the capacitive thin film polymer sensor by Vaisala.

Kurt Künzli immediately recognized the enormous potential of this innovative sensor and decided to establish the official Swiss representation for industrial, meteorological and environmental measurement solutions. This was the starting signal for a success story that continues to this day.

Since our founding almost five decades ago, we have continuously evolved and are proud to be a leading provider of high quality measurement instruments and solutions in Switzerland. Our commitment to precision and quality has made us a trusted partner for companies in various industries.

A special feature of our company is the fact that it has been in family hands since its foundation. The passion and commitment of Mr. Kurt Künzli have been carried on into the second generation of the family, and this tradition continues to shape our corporate culture today. We firmly believe that our family roots allow us to build long-term relationships with our customers and respond to their individual needs.

Our journey began almost five decades ago, and we are proud to look back on a long history of successful cooperation. We would like to express our sincere gratitude to our customers and partners who have placed their trust in us over all these years. The future certainly holds many more exciting challenges and opportunities for us, and we look forward to mastering them together with you.
