Ph probe questions for Apex Users

[Emoney]

Looking to set up a calcium reactor and would like to run if off the apex..Do i need a PM1 or can i run a additonal Ph probe off the stock Apex..??

I run one off the ORP probe connection. My stock Apex setup runs two pH probes, I think it was just something in configuration to swap it from ORP.

Run the Extra probe on the PH/ORP and configure it to follow your CARx.
If you need more BNC connectors Apex sells expandable units.

If you have the Apex system, you can use the ORP input for pH. However, if you have the Apex lite or if you already have an ORP probe connected, you'll need to connect a PM1 for a second pH probe.
