I know the Blue lab web page has a lot of that kind info in there. With my set up i can only replace the PH probe and i do that every 2 years.Thanks guys. I plan on using it in a RDWC epi full time. I did last run for 3 months straight. Probably back to back runs so the probes will never get a break. Sounds like I may be replacing probes yearly or more
