The best wrong tool we have is a conductivity meter.
It's doesn't actually measure silver, but gets you a pretty good guess and
a good guess is all that's needed.
To "actually measure" the silver takes an Atomic Absorption
Spectrophotometer [ tens of thousands of bucks and an eddication to run it]
A Hatch Colorometer does a decent job starting at about $5,000

Where are you getting the distilled water from? And note that meters only
tell part of the story. They do NOT measure the presence of particles or
organic impurities. So as it says below "a cup of distilled water that
contains a tablespoon of sugar and finely powdered glass may display a ppm
reading of near zero even though its obviously not pure."

Heres some stuff about meters...
Many people think that a PPM meter gives a definitive reading of the
purity of water. This is not true. A ppm meter can only detect those
dissolved impurities that raise the electrical conductivity of the water.
So a meter can only determine the ppm of the dissolved NON-ORGANIC
impurities (e.g. dissolved salts) because only these impurities raise the
conductivity. It cannot detect the dissolved ORGANIC impurities* that may
also be in the water (e.g. sugar or rotted leaf litter). Nor can a ppm
meter detect the microscopic solid particles that may be in the water
(i.e. the grit). So a cup of distilled water that contains a tablespoon of
sugar and finely powdered glass may display a ppm reading of near zero
even though its obviously not pure.
So, when using a ppm meter to measure water purity, you have to know if
the dissolved organic impurities and the fine particles have been removed
along with the salts. The only way to remove all these impurities is with
a high quality reverse osmosis/deionisation system or with careful steam
distillation.
The shortcomings of meters mentioned here should especially be considered
when measuring the purity of rain water. Although the rain water may
initially be pure, it can become significantly contaminated by organic
impurities in the gutters and the tank. Although these impurities are not
detectable by the meter they can have quite a detrimental effect on
colloidal silver production.
(* One qualification to the comment above about the 'non conductivity' of
organic impurities concerns the presence of acid. Any acid raises the
electrical conductivity of water and can induce a completely meaningless
reading on a ppm meter. While organic impurities usually do not register
on a ppm meter, a few drops of, say, acidic lemon juice in a glass of
water will produce readings in the 100's.)
