Hey buds...I ordered a cheap ph meter of amazon recently and it came with 2 calibration "dust crystal" solutions...a ph 4.0 and a ph 6.86.
What I want to know is how exactly do I go about calibrating these things...
how much of these solutions do I add to water... reason i'm asking is because if I add a touch to a shot glass of water I get a different reading then when I add the same amount to a full glass...someone help me out...
