“Be sure.” This motto is in equal measure a slogan and the key to the success of Testo, whose headquarters are in Titisee in the Black Forest. This globally active high-tech company is an expert in highly precise measurement technology and innovative measurement solutions. Testo’s customers range from the local contracting company around the corner to the global pharmaceutical firm. They all have to make important decisions in their daily work. And that’s when they depend on the measuring instrumentation, solutions and services from Testo. Because these ensure that foods are safe, heating systems work correctly or that compliance is fulfilled in the production of drugs. This allows our customers to increase the quality of products and services while saving time and resources. From its beginnings as a small manufacturer of temperature measuring instruments, today Testo is a global concern. Testo SE & Co. KGaA has a presence on all continents, with 37 subsidiaries and more than 80 trade partners. An average annual growth of over 10% since the foundation of the company in 1957 and a current turnover of 466,5 million euros clearly demonstrate that the Black Forest and high-tech systems are a perfect match. Testo has a strategy of sustainable and profitable growth, and not least the extraordinary commitment of the staff to thank for this success. Roughly 3,900 Testorians worldwide research, develop, produce and market for the company with passion and expertise. The above-average investments in the future of the company are part of the recipe for success. Testo invests about a tenth of its annual global turnover in Research & Development. Whether in agile project management or the attention to megatrends such as the internet of things – dynamics and orientation to the future characterize Testo. This is one of the reasons the company is regularly awarded the title of one of the most innovative medium-sized firms in Germany.
