From Dr. Lange...

The combination of innovation and customer relation is our strength. Thanks to this strategy we are proud to belong to the worldwide leading companies for many years now.

Today Dr. Bruno Lange GmbH & Co. KG in Berlin and Düsseldorf employs 650 people in the field of analysis. We are competent in development, production, marketing, sales and service in the fields of measurement technology and reagents. An international network links us to subsidiaries and dealers in the Benelux countries, Denmark, Great Britain, France, Italy, Austria, Poland, Sweden, Switzerland and Spain as well as other long-term trading partners in many more countries.


It's actually very simple: We want to provide you with the right water analyses. But there is no "turn-key solution": only you can decide what is right for you, by examining your requirements and demands from your daily analysis. A customized and suitable solution from a single source needs extensive competence in all aspects of water analysis. And exactly this is what HACH LANGE stands for as THE platform in Europe. Its basis is the ideas and know-how of HACH and LANGE. It also integrates our company's other strong partners - like BÜHLER, GLI, LACHAT, POLYMETRON, RADIOMETER ANALYTICAL and SIGMA - under the motto: The whole is more than the sum of its parts.
