Silver/Sulfide Half-Cell Ion Selective Electrode (ISE) HI4015
The HI4015 is a solid state, half-cell ion selective electrode (ISE) for the determination of silver (Ag+) or sulfide (S2-) in solution. The silver/silver sulfide sensing pellet produces a potential change due to the ion exchange between the inorganic pellet membrane and the sample. The internal sensing elements are housed within a durable epoxy body. The HI4015 is ideal for a variety of applications in water conditioning, environmental monitoring, and industrial processes.
- Silver detection from 0.11 to 107,900 mg/L Ag+

The HI4015 silver/sulfide selective electrode is a potentiometric half-cell sensor housed within an epoxy body. The internal elements are isolated from the sample by a compressed silver/silver sulfide sensing membrane. This solid-state sensor requires a separate reference electrode to complete the measurement system.
Hanna’s solid-state half-cell ISEs are designed for use with the HI5315 reference half-cell. The reference half-cell features a cone style junction. The skirted cone geometry of the reference forms the liquid junction with the test solution at the tip of the junction cone, producing a highly stable reference potential and consistent flow rates of electrolyte into the solution. A simple press of the top portion of the ISE makes it easy to empty the electrolyte fill solution and replace when necessary.
Measuring all solutions with a constant ionic strength reduces the margin of error between measurements. The HI4015 silver/sulfide solid-state ISE can measure silver from 1µM (0.11 mg/L) to 1M (107,900 mg/L) and sulfide from 0.1µM (0.003 mg/L) to 1M (32,100 mg/L).
