Bio-Pool® Libra Duo pH & Chlorine Dosing Controller

Bio-Pool® Libra Duo – Automatic pH & Chlorine Dosing Controller

The Bio-Pool® Libra Duo is a complete two-channel water treatment controller that automatically regulates both pH and chlorine (ORP) levels in your pool. It continuously measures both parameters and activates the corresponding dosing pump only when a correction is needed – delivering a perfectly balanced water chemistry with zero manual intervention. Compatible with peristaltic dosing pumps and designed for wall mounting near the filtration system.
