Apex PH settings

[Hitman]

Just set up my first Apex. After I went through the steps to calibrate the probe I saw a box asking if I want temp adjust on or off. What should it be set at? It was in the disabled position when I calibrated the prob so if I turn it on will I have to recalibrate it?

If you are using the pH probe from the base unit, and the temp probe from the base unit, and they are relatively close to one another, then yes, you want temp compensation. I think you do *not* want it if you are using like a PM1 pH, and the base unit temp probe. (Or if you are using pH probe in a calcium reactor)

Same for salinity.

They are all in the Neptune probe holder. Should have recalibrate them as I enabled temp comp ?

I think so? Been awhile since I did mine. You do want to enable that though, it increases accuracy by quite a bit.

Thank you! I'll order some calibration fluid and get them redone.
