Rola-Chem system components are designed to keep your pH and ORP metering system running properly and accurately. 

Pool controller pH and ORP sensors or probes, can fail at any moment, and when the pH probe is failing, it can cause the ORP probe to give false readings. Check your probe calibration every 4-6 weeks, and for longest probe life, keep your Rola-Chem probes and wire contacts clean, and pool cyanuric acid at 30 ppm or less. Improper voltage or grounding can also shorten a Rola-Chem probe life.
