Description

Overview

The Hach SC4500 is a universal digital and analog controller for water and wastewater process instrumentation. It shares the same footprint as the SC200 and works with your existing Hach digital SC sensors, so you can modernise your measurement system without replacing your current sensor inventory. Extensive analog and digital connectivity, together with intelligent instrument and data-management features, make it a future-ready platform.

Built-in Prognosys predictive diagnostics give operators confidence in every measurement and help reduce the risk of unexpected downtime. The SC4500 communicates locally with SCADA or a PLC and supports mobile, Claros-enabled connectivity, all managed from a 3.5-inch colour touchscreen inside a rugged IP66 / NEMA 4X metal enclosure.
