Hayward - Crystal pH Control Probe Kit

Crystal pH Control Probe Kit

The Crystal pH Control Probe Kit is a complete pH measurement and control probe kit for Hayward-equipped pool systems. It enables continuous, real-time monitoring of the pH level in the pool water and, when connected to a compatible Hayward controller, triggers automatic dosing to keep the pH value within the optimal range.

Consistent pH control is fundamental to effective pool water treatment — incorrect levels reduce the efficiency of chlorine and can cause eye irritation, scale formation and equipment damage.

What’s Included

• Crystal pH probe with immersion fitting
• Connection cable for Hayward NG control systems
• Probe holder/flow cell for inline installation

Installation & Calibration

The probe is installed in the pool circulation line in a dedicated flow cell, where it is continuously exposed to a representative sample of pool water. After installation, calibrate the probe using the supplied buffer solutions before first use. Recalibrate every 4–8 weeks and replace the probe element every 1–2 years under typical conditions.
