Has anyone ever tried to read an ORP probe or pH probe with the basic stamp? I wonder if there are any interface IC's available for this. Any advice would be greatly appreciated. Thanks!

show links and specs for what you want to do. How do the output their data? Thanks!

Ideally, you want a probe that puts out either an industry-standard analog signal such as 4-20 mA or 0-10 v. Then you can add an a/d converter to your stamp and read the probe signals.
A smarter probe may offer you a serial data output which is very easy to use with the Stamp using the SERIN command.
I've used both and they each work well.
