Newbie Question: Apex Gold ORP???

[Eric81]

Recently got the Apex Gold Kit. Got everything set up, but can't find my ORP number. Is it the same probe as pH2? what the heck is pH2???

Ph2 is another ph probe. You should be able to rename it what you want. I'm not sure on the ORP.

Is there a red probe?

 

[Eric81]

Yes it is the red probe....plugs into the pH/ORP port. The pH2 reading 2.62, while my other ph probe is calibrated and accurate...

On the Apex, there are two BNC connectors. The one which is labeled pH/ORP is modal (meaning selectable); it can be configured for use with a pH probe or with an ORP probe. If you are seeing a pH2 reading, then you need to disable pH 2 and enable ORP.

This video shows how to change the port from ORP to pH2. You need to do the opposite, but this video should get you on the right track.
