Meters do not measure PPM, they detect conductivity.
Hot water is more conductive than cool water.
To be more precise, electrons are carried in a liquid by electro-chemical ion exchanges.
Heat speeds up the chemical reactions.

I have noticed that if I heat my finished CS (microwave or stove) the ppm increases exponentially. An 8ppm solution increased to 16ppm when heated to near boil and returns to 8ppm at room temp. Is this just the separation of large molecules to smaller when stimualted by heat? Lou
