I am running atlas scientific ph probe , which are pretty good but expensive (70$). I just received american marine pin point probe, I'll be using this to test the ph board and base board. I'll keep you posted how it performs. This probe is probably the cheaper salt water rated probe. BRS should be somewhere in the middle.
If things go as expected I should be able to compare all the boards (ezo, baseboard and ph board) as well as the two probes (atlas scientific and american marine)
