Calibrating multiple Apex pH probes

[jasonrusso]

I have 2 tanks, both have Apex units. When pH probe calibration time comes, can I do both probes with one calibration packet? So if I open a 7 and 10 and do one tank, can I turn around and then do the other tank while they are still open? I don't think a couple of drops of water from one tank will dilute the solution.

Any thoughts?

I do this, I just do it as quickly as possible and dry the probes off as best I can between solutions. Just make sure you double check the accuracy of the probes with the packets after you finish.
