TFA Dostmann is a traditional German company founded in 1964 by Heinz Dostmann. While the brand takes great pride in its "Made in Germany" heritage for its mechanical instruments (which are still produced at their headquarters in Wertheim), their digital and electronic product lines, like this thermo-hygrometer, are typically manufactured in East Asia—specifically China—to remain competitive. The company maintains strict quality control and oversight through its own branches in Hong Kong and Shanghai.

The brand remains a family-owned business, currently led by Axel Dostmann. It has grown from a specialized factory for valves into one of Europe's leading manufacturers of meteorological measuring instruments, distributing its catalog of over 1,000 products to more than 80 countries worldwide.
