A genuine Hayward replacement pH probe engineered to deliver continuous, accurate pH monitoring as part of an automated pool water treatment system. Designed for use with Hayward’s Sense and Dispense chemical automation systems (AQL-CHEM, AQL-CHEM-UPG) and compatible with AquaRite Pro salt chlorine generators (AQR-PRO-SD, HPC-4-ACT-RC), this probe restores the precision your dosing system depends on to keep water balanced and chlorine working at full effectiveness.<\/p>\n
pH sits at the heart of effective salt electrolysis: when it drifts, chlorine efficiency drops and swimmer comfort suffers. This Hayward probe continuously feeds live pH readings to the controller, allowing the system to trigger acid or pH-minus dosing automatically and hold values in the optimal treatment window. Replacing a worn or drifting probe with a genuine OEM part ensures the signal chain from sensor to dosing pump remains reliable.<\/p>\n
The probe is a direct, like-for-like replacement for Hayward Sense and Dispense and AquaRite Pro installations \u2014 no adapters or rewiring required. It is not intended for Hayward models that do not incorporate pH control (such as the Salt & Swim 2.0 or AquaRite Flo basic), so confirm your controller model before ordering. Professional installation is recommended to preserve system calibration and any applicable warranty coverage.<\/p>\n
pH probes are consumable sensors: over time, the sensing membrane can become fouled or slow to respond due to scale, biofilm, or general wear. Regular cleaning of the probe tip \u2014 with the controller and feeders off and the flow cell isolated \u2014 keeps readings accurate between replacement cycles. Keeping the tip moist at all times during handling protects the sensitive glass membrane from drying damage.<\/p>","protected":false},"excerpt":{"rendered":"
