Dealer-direct Rola-Chem. Continuous pH and ORP, dosing only when the water asks.
The RC555XXP Digital pH/Dual ORP/FAC PPM Pool Controller reads your water continuously and doses only when the water asks for it. It runs a dual ORP plus free-available-chlorine PPM sanitiser channel alongside pH, holds the reading through a five-minute analyzation period so a single splash never triggers a feed, and drives the feed pumps or solenoids directly from its own switched outputs.
Check which configuration you need — controller only, controller plus flow cell kit, or the full package with probes — because the probes and flow cell are the parts most often already on site. Probes are consumable and typically need replacing every 12 to 24 months. Confirm 120V power is available at the panel location.
This product is offered in 2 configurations. Choose the configuration that matches your installation before adding to cart — configuration is set at the factory.
Free tools built for pool owners and pros. Work it out yourself, then call and we'll double-check.
