Hanna also makes the HI 93737. Which is advertised as specifically to measure silver. The specs are a bit low for our purposes (0.0 to 0.6 mg/L) but the chemist should be able to tell you the conversion factor that is used and we could go from there. If it is only a matter of measuring current and converting it to get an accurate reading then it would be a piece of cake to come up with a circuit to do this.
