Quick overview
- Heavy duty build The heavy duty version of the Rola-Chem ORP probe, made for continuous commercial service.
- Eight foot lead An 8 ft lead gives room to place the probe away from the controller.
- Digital or analog Works with Rola-Chem digital and analog controller systems.
- ORP measurement Reads oxidation reduction potential, the value the controller uses to judge sanitizer activity.
- Genuine Rola-Chem Factory part 550136, not a generic probe.
- Probes are consumable Every ORP probe drifts and eventually stops reading true, so replacement is routine maintenance, not a failure.

Product details
The Rola-Chem 550136 is the heavy duty ORP probe with an 8 ft lead, made for Rola-Chem digital and analog controller systems.
What it measures
ORP, oxidation reduction potential, is the reading a controller uses to judge how actively the sanitizer in the water is working. It is a better guide than raw chlorine concentration, because it reflects what the sanitizer is actually doing. The controller feeds chemical based on that number, so the probe is the piece the entire automated loop depends on.
When to replace it
Probes are consumables. The sensing element slowly loses response, readings drift, and calibration stops holding. Once a probe will not stay calibrated after cleaning, it is done, and the controller is dosing on bad information until it is replaced.
Note on the pair
ORP and pH are read by separate probes. If your controller manages both, this listing covers the ORP side only; the matching 8 ft heavy duty pH probe is a separate Rola-Chem part.
