I have a pH probe that dried out. Can I re-soak it and get a reliable reading.
What happens when a pH testing probe dries out? Is it possible to soak it again and get reliable readings?
Should I replace it? It’s just a blue lab pen that I bought for my hydroponic garden. I got rid of the garden and was wanting to use it for other things in the kitchen, canning and whatnot, but it dried out. I’ll toss it if it’s not safe, anyone have a rec for a pen for kitchen use if the one I have is done?
