So I have a circuit to connect a probe to, but I can not determine which probe to purchase. From what I can read the EC of saltwater is 54,000uS/cm.
I have read on several threads that people are using the conductivity electrode SDL-1 from

However from what I can tell, it would not read high enough. Anyone else using one of these probes or have a different source for probes?
