The PPM meters are usually calibrated for CaCO2 at 2uS/PPM. For
ionic Cs Ivan says 0.6, Trem 1 (or lately maybe 1.6) and I and some
others say 1.6uS/PPM.
With the high ratio you are getting I would suspect your sample had
a lot of metallic silver in it (not ionic) from running for an excessive
time without circulating, allowing crystallization. The PPM and PWT
meters will not register any metallic silver, as they do not conduct in
a suspension. The true meaning of PPM is by weight so the lab may
certainly be correct, while you measured only part of the mix. Drop
a dime in a glass of DW and you get high PPM but no conductivity!
We do free testing and report the uS and test for metallic silver also!

## Ohh Robert, that's a sore one. My DiST 1 PPM meter doesn't agree with
the lab reports at all. It's supposed to read straight PPM. I get 14 at
second shutoff... about 2 to 2 1/2 hrs run time. The lab says 45.5 PPM
silver by weight in 2 hrs.
