Description

The IPS Controllers SXORPG is a replacement ORP sensor with a gold sensing tip, the version listed for salt pools.

What the sensor does

A chemical controller decides when to feed sanitizer from what its ORP probe reports. Oxidation reduction potential is a measure of how actively the water is sanitizing, not a chlorine count, so the controller leans on the probe being honest. As a sensor ages the readings drift, and the controller keeps dosing to a number that is no longer real.

Choosing the right tip

IPS lists this sensor with a gold tip for salt pools and a separate sensor with a platinum tip. They are different part numbers, so match the tip to what the system was built with. The pH sensor, SXPH, is a separate item again.
