TDS conductivity meters have a far from perfect temperature
calibration. They are only of limited accuracy over a fairly limited
temperature range.

Forgot to mention, I use a simple TDS meter.

Excellent feedback Ode, I have noticed that there are different
meters (PWT, TDS and others) and read that the typical meter
is claibrated for NaCl and not Ag. What do you recommend so that
I can get a resonable consistance in my solutions.
All else being consistant i.e. Water purity, water aggitation and
14V 360mA power source.
Thanks, Lou

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
