Pretty sure you can't.

The 2 connections on your base unit work like this:

1 = pH only.
2 = pH OR ORP. (You have to select which one in the setup menu)

So you can either run 2 pH, no ORP, or 1 pH & 1 ORP.

That is to the best of my knowledge at least.

This should allow me some expansion ?

It would if you've got one... I'm guessing it's part of the Gold package?

[Doug]

Apparently not.

What's another $90...

[Doug]

Agreed. Perhaps I can change the couple hundred extra for useless parts for one of those.....
