Your Process.
Under Control.

Why over treat? Simply set your effluent limit and let RTC do the rest.

Hach Real-Time Control (RTC) Modules make controlling your process easy. Setting your desired effluent limit is all it takes. Based on that information, RTC automatically adjusts your process to achieve and maintain consistent effluent. By programming RTC with your values, you can ensure you don't spend more on energy and chemicals than is absolutely necessary. Imagine how much you can save by avoiding over treatment. That's your process under control.
