Milwaukee salinty checker

[Joe0813]

I just ran out of the steam distilled water that came with the checker to zero/calibrate the unit. can I go to Walmart and just buy distilled water or does it have to be the stuff they give you?

I've only ever used RO water to calibrate. Never had a problem.

Use RO like Zeebies suggested, thats what I use too
