Just checking: Calcium Reactor pH Probe Calibration

[bdare]

Hello all,

I'm setting up a Calcium Reactor for the first time and just want to make sure I'm doing it correctly. When calibrating the pH probe should we use the 4 and 7 calibration fluids?

Thanks,
Ben

correct.

Doesn’t actually make all that much difference since you are measuring quite close to neutral pH. Probably calibrating with 7 and 4 will give you a little transient precision below 7, but it’s pretty minor. I’ve calibrated with both 7 and 4, and 7 and 10. Both work fine for our purposes.
