The HI4009 is a solid state, half-cell ion selective electrode (ISE) for the determination of cyanide (CN–) in solution. The silver halide sensing pellet produces a potential change due to the cyanide ion exchange between the inorganic pellet membrane and the sample. The internal sensing elements are housed within a durable epoxy body.
The HI4009 is ideal for a variety of applications in plating, wastewater, and agriculture.
