Our Heritage

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