About Testo

Testo was founded in the Black Forest, Southern Germany, in 1957. The first product was an electric thermometer. 60 years on, we are now a market leader on all continents, with a customer base that is as diverse as our product range: From local trades around the corner to global pharmaceutical groups, every type of business is represented. And they all have to make important decisions in their daily work.

Measuring instruments, solutions and services from Testo give them the confidence that they are making the right decision, time and time again. This ensures 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. And whenever it comes down to it, and you have to make important decisions, you can rely on Testo – with certainty.

Be sure. Testo.
