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
Actually you can use an atomic absorption spectrometer, that is what
Frank uses, or a spectrophotometer (also called a photospectromemter ),
which is what I use. I have the Hack unit myself, but requires digestion
of the silver by nitric acid first.
