I purchased an Pinpoint pH probe which I never got around to setting up. I pulled off the tip and found the gel has dried up.
Is there a way to test to test the probe to determine if its still functional?
If not, I'm planning on replacing it with a Milwaukee Instruments MA911B/2 Double Junction Ph Electrode from amazon.com

Will this work on my Apex classic?
Thanks in advance.
