Hach Lange Turbidimeter

This device is a professional turbidimeter, specifically identifying as a model from the Hach or Hach Lange series, used for measuring water clarity in laboratory and industrial settings.

The brand Hach was originally established in Iowa, USA, by Clifford and Katharine Hach. Over decades, it became a global leader in water quality analysis. The product seen here is part of their high-precision analytical lineup, which is largely manufactured in the United States and Germany to maintain stringent calibration standards.

Today, Hach is a key brand within the portfolio of the Danaher Corporation, a leading American science and technology innovator. The ownership reflects a transition from a family-founded specialist company to a core component of a multinational conglomerate focused on environmental and life sciences diagnostics.
