Yesterday and Today
After more than 55 years in business, a significant change took place in our company in 2025. The Dr. Wiesner Steuerungstechnik GmbH became the Wiesner Prüftechnik GmbH.
Even though our company name has changed, the values that have shaped our company for more than half a century remain unchanged. The expertise and experience that we have accumulated over more than five decades will continue to form the basis of our actions.
After many successful years in mechanical engineering, we are now setting a new focus in our corporate development, increasingly concentrating on the construction of series devices – innovative solutions precisely tailored to your needs. We can also make minor modifications to existing test benches or components to optimally adapt them to your requirements.
With the decision to increasingly focus on the construction of series devices, we are returning to our roots. Our success story began in 1978, ten years after the company’s founding, with the development of one of the world’s first series leak testing devices, Type W6.41, which was still purely pneumatically controlled.
When it comes to machinery and equipment, we will primarily act in an advisory and mediating capacity in the future. Our goal is to optimally support you with our expertise and our large pool of cooperation partners in the planning, optimization, and implementation of your projects.
Our products continue to bear the trademarked name, firmly established in the industry, Dr. Wiesner, which stands for the highest quality and reliability.
