, well that didn't explain anything
I really don't buy that "storage solution can dry up in the shipping".. I'm pretty sure there was never any fluid in the tiny cap that comes with it. And if they are telling the truth then why on earth would they make a loose-fitting cap that could hold all of 1 ml of solution
I guess I'll have to look into how these electrodes actually work to see if I can figure this out. I can understand that it would take a bit longer to get an accurate reading but I just don't see how AIR could kill it!
