So I dipped the meter in the ph 7 and it read ph 7.
Then i dipped the meter in the water and it changed to ph 7.
Then I read more about a buffer solution vs. water. Water can easily get it's pH changed with just a drop or two from a buffer solution.
Fun. Brings back the old days in chemistry where I learned that.
