ISE: Silver/Sulfide - Van London

A sensor specifially designed to measure either 0.01 ppm to 107,900 ppm (10^-7 M to 1M) concentrations of Ag⁺, or
0.003 ppm to 32,100 ppm (10^-7 M to 1M) concentratios of Sulfide (S_-2).
Applications include, but not limited to: Sewage effluent, Soils, Sediments (Sulfide), Plating Baths (Silver), Photographic Fixing Solution (Silver).
