Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I found it very challenging to maintain the electrode longerterm and finally gave up


So, like metering sugar in blood levels there are cheap enough disposable sensors might it be disposable PH sensors exists too? Did not tried to search for it, but it would be logical they exist.
