Hi,
We tried one and it did not work with colloidal silver. Was told it was for
use with dissolved silver such as in waste treatment plants etc. The sample
measured the same as the blank or as much as 25% of the readings done on
our CS by Kimball Labs as I recall. Would have been a good way to test if
it had worked. All readings were not repeatable and were way off the mark.
We even tried digesting the silver in nitric acid to see if that would
help. It didn't.

How many tests in each Hanna lot?
The thing is a dedicated single-element spectrophotometer. They save big
bucks by having a single color LED as the light source instead of the
precise opto-mechanics needed to precisely align a diffraction plate to
produce a wide range of frequencies.
This would make it feasible for more home CS makers to measure the strength
of their sol.
The glassware is still going to cost a few hundred more though...
Dilution will be based on the concentration of the silver you are making; I
try to dilute to the middle of the range of the reagents.

Well that's not bad is it. Damn site cheaper than Hanna.
Do you need to dilute CS 10 -100 :1?
Ivan.

One might be able to use Hach reagents.
