Can you hook up two probes to one brain? I dont remember seeing two connections.
Can you hook up two probes to one brain? I dont remember seeing two connections.
If you have a classic or 2016, you can if you choose not to use an ORP probe. If you want both a second pH and ORP, you need a PM1 module.
For a Jr, there is not a second port, so the only way is with a PM1.
You might be an engineer if...You have no life and can prove it mathematically.
