It measures the ionic content, not the colloidal content. > Transmittance is the measurement of light > passing through the sample.

But there is no way to corrolate the amount observed vs the concentration since the absorption goes up with the particle size. The absorbed wavelength goes up with the particle size, and thus one CAN make a good estimation of the concentration using a scanning specrtrophotometer, as long as a UV one is used. These can be purchased for about $6,000. Marshall -- The Silver List is a moderated forum for discussing Colloidal Silver.
