Problem with PH reading
Posted: Mon May 06, 2013 2:27 pm
I think I may have a bad ph probe. This would be the second probe gone bad. I have tried calibrating the probe, testing with water outside of the tank to eliminate any possible stray voltage, and resetting an restoring the code in my RA. I get a reading of 1.26-1.28 regardless of what water I test it with.
Help?
