Automatic pH and Chlorine (Redox) Digital Control -EV

EV Digital pH Control System

Metering pumps are a type of pump whose purpose is to inject a liquid (in swimming pools it is normal to inject a liquid demineraliser, pH increaser or liquid chlorine) into a fluid line.

The equipment comes with a schuko connector outlet for the placement of an external chlorine control (redox).

The peristaltic pump has a flow rate of 4.5 L / h and injection properties at pressures up to 2.5 bar

Features DOUS EV automatic control:
