Testo was founded in Lenzkirch, in the Black Forest region of Germany, in 1957 and has since designed, developed, and manufactured portable test and measurement instrumentation and solutions. Backed by 60 years of measuring engineering experience, testo's mission is to provide the highest quality, service, and value.
Testo's first product manufactured was a simple electronic thermometer. Today, the product line has expanded to include a large variety of temperature measuring instruments, such as data loggers, air velocity meters, humidity and dew point meters, refrigeration service analyzers, multifunction instruments, stack gas analyzers and air emission monitors, water analyzers, tachometers, sound, pressure, and light meters, and thermal imagers.
