Description

The IPS Controllers SXPH is the pH sensor for IPS controllers. It is the blue top probe, and it measures the pH in the pool or spa.

What it does

The controller decides when to feed acid or base from what the pH probe reports. When the probe is accurate the water stays in range on its own. When it drifts, the controller keeps dosing against a reading that is not true.

Before you order

Check which probe you need. The pH sensor is the blue top part shown here. The ORP sensors in the same range are separate items, so order by the measurement rather than by appearance alone.
