Product details
The Rola-Chem 550135 is the heavy duty pH probe with an 8 ft lead, for Rola-Chem digital and analog controller systems.
What it does
A chemical controller decides when to feed acid based entirely on what the pH probe tells it. That makes the probe the accuracy limit for the whole system. When one ages past the point where cleaning and calibration bring it back, the controller keeps dosing confidently on numbers that are no longer true.
Before you order
This is the pH probe, not the ORP probe, and the ORP version is a separate part. The lead is eight feet, so check the run from your probe location back to the controller.

Questions and answers
What people ask about this product, answered by our pool techs.
Is this the pH probe or the ORP probe?
pH. The heavy duty ORP probe is a separate Rola-Chem part.
How long is the lead?
Eight feet.
Which controllers does it work with?
Rola-Chem digital and analog controller systems.
How often do pH probes need replacing?
They drift as they age. When a probe will no longer hold calibration after cleaning, it has reached the end of its life and the controller is dosing on bad readings.
