how does it work??
just kidding
One would, or better put I would assume that if a bottle of pinpoint was sitting around for a while, and it evaporated some due to age, that it would result in calibrating your refractometer high. Meaning that if you followed its results your actual system salinity would end up on the high side of your intended target...not the low side.
That said, I have had the opposite effect with a bottle that was a couple of years old, and cant help but wonder how, and if the stuff being old on its own could possibly sway the results the other way, and the inaccuracy maybe had nothing to do with evaporation at all, but some other reaction due to age.
Either that, or the brand new bottle I recieved is off two full points, or the original bottle has been off all along.
If anyone followed that rambling..........thoughts??
