So I want to calibrate my pen it says put the solution into di water , now ph water can be 5.5 to 8 apparently 7
so how do I know if my base water is correct when adding the 4ph and 6.8ph powder ?
when I do this I am told I need to adjust my pen 0.8
but if the base water is out 0.8 to their water the result is skewed?
I mean my tap always reads 7.5 and it does now but if I adjust this pen to the solution then my tap is going to be like 8.4 which I k ow it isn’t
what do I trust
