You calibrate your instrument to the standard and then want to immediately test the ph of tap water. Or something. Isn't that what it's supposed to do? Why would you suspect the tap water results if the cal. looked ok? Assuming temps are correct, or whatever.right also i am 100% legal so i'm not really worried about raising suspicion i just wanted to know if i should be worried my ph pen is not working correctly
Just curious. I've been toying with the idea of getting something, but I'd rather have nothing than data I couldn't trust. Curse you hydrogen!
