Hayward - pH Probe for Sense & Dispense / AquaRite Pro - 7040163

Hayward – pH Probe for Sense & Dispense / AquaRite Pro

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.

Sensor accuracy & water chemistry control

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.

Compatibility & fit

The probe is a direct, like-for-like replacement for Hayward Sense and Dispense and AquaRite Pro installations — 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.

Probe care & service life

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 — with the controller and feeders off and the flow cell isolated — keeps readings accurate between replacement cycles. Keeping the tip moist at all times during handling protects the sensitive glass membrane from drying damage.
