Can I calibrate 2 ph probes with 1 packet?

quick question. I picked up the milwaukee 7.01 and 10.01 solution packets and want to know if I can calibrate two probes at the same time or back to back using the same solution.

I do it all the time

great, Iv been using my Apex lab probe and now I added another more generic probe that came with my kalkwasser reactor and the two conflict by more than a little.

Even after a calibration they still read a lot different?

the non apex one came with its own digital reader and it changes way more often than the apex. It also has variances that show .20 differences from my apex. at other times they are more similar. not sure what to believe lol

Always a good idea to compare the probes to a test kit.
