History and

Who We Are 

Our Heritage

In 1947, Clifford and Kitty Hach invented a whole new way to think about water analysis. In 2004, Hach merged with an equally committed organization —Dr. Bruno Lange GmbH of Germany — to expand our water analysis solutions and become a truly global organization. Today, Hach offers more products, more chemistries, more services, more software, and more expert advice to help you with your water analysis than ever before.
