Hayward OmniLogic Sense and Dispense Water Chemistry Automation, HL-CHEM

Hayward OmniLogic Sense and Dispense (HL-CHEM) automates pool water chemistry by monitoring ORP (sanitizer) and pH and adjusting chlorine and pH levels automatically. It’s an add-on for all Hayward OmniLogic automation systems and works with either a salt chlorinator or a liquid chlorine feed tank.

Includes ORP and pH sensors plus 120V and 240V pigtails to power a pH-reducing device (peristaltic pump or solenoid valve, not included). For a plug-in option, Hayward’s AQL-CHEM2 (120V) or AQL-CHEM2-240 (240V) CO₂ dispense kit connects to the pigtail to lower pH by injecting CO₂.
