Pre-engineered drinking-water distribution panel: pH, conductivity, turbidity, chlorine, pressure and temperature on one SC4500.
The Blue Drop panel brings the key distribution-network measurements onto one panel and one controller. Connected to the Liquid Science IoT platform, readings reach a live dashboard with alarms, so operators see compliance in real time instead of waiting for grab-sample results.
