Anyone out there doing ASTM F-2170 testing? I would like to know what the rate is in your area. Realistically it should be the same world wide.
Also, if you are are you using a re-usable probe or the Rapid Rh? If re-usable what are you paying to get it re calibrated every 30 days per ASTM F-2170? And do you charge more for Rh than Ca Cl or the same?
