I ordered my calibration liquid about 2 weeks ago, and it has yet to come in. I have a small pack calibration solution, but I think its already been compromised with my resevoir liquid and not accuate. I was wondering, I know a lot of bottled water manufacturers put the ph of their water on the labels. Now could this be used to calibrate? I just wonder if they are accurate. Im using a cheapy ph meter, and im afraid it might be going out of wack.
