Hi, Since I don’t have any experience with that probe, I wouldn’t know. But what I can say about the probe in my project, is that readings are not accurate after being submerged for long periods.

OK, so their Consumer Grade or Lab Grade should work with the basic board. Just have to check the connector. Or I could also still use the 15 years old probe that is still working with my swimming pool...
