Turbidity Analyzers

Although turbidity analyzers was developed for controlling and monitoring drinking water, a turbidity measurement is also required in wastewater plant more and more to achieve sustainable society. Yokogawa started turbidity business since 1959, and our analyzers supplying safety water and saving water pollution around the world. You can find the best solution thanks to excellent technologies proven by experiences.
