Hanna HI4012 Lead/Sulfate Half-Cell Ion-Selective Electrode (ISE)

The HI4012 is a solid state, half-cell ion selective electrode (ISE) for the determination of lead (Pb2+) in solution and indicator for sulfate in titrations. The lead 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 HI4012 is ideal for a variety of applications in the plating industry and environmental monitoring.

The electrode features a lead sulfide sensing pellet that generates a stable potential based on ion exchange between the inorganic membrane and the sample solution. This design ensures reliable and responsive measurements, even at low ion concentrations. Its solid-state construction eliminates the need for internal filling solutions, reducing maintenance requirements and simplifying operation.

Encased in a rugged epoxy body, the HI4012 offers excellent chemical resistance and mechanical durability, making it suitable for continuous use in harsh industrial and laboratory environments. The robust design enhances electrode longevity while maintaining consistent analytical performance over time.
