HI-4008 Cupric Half-Cell ISE

The mixed cupric sulphide/silver sulphide sensing pellet produces a potential change due to the cupric ion exchange between the inorganic pellet membrane and the sample. The internal sensing elements are housed within a durable epoxy body.

The HI-4008 is ideal for a variety of applications in plating, wastewater, and industrial processes.

• Solid state sensor
• Detection from 0.065 to 6,355 mg/L Cu2+
• For use with HI-5315 reference half-cell

The HI-4008 cupric ion selective electrode is a potentiometric half-cell sensor housed within an epoxy body. The internal elements are isolated from the sample by a compressed cupric sulphide/silver sulphide 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 HI-5315 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.

For the HI-4008 to measure cupric ions accurately, it is important that the ionic strength of the standards and sample be adjusted to a high and constant value with the HI-4000-00 ionic strength adjuster (ISA) solution. The ISA ensures that the activity coefficient is constant so the concentration of free cupric ions can be measured. Measuring all solutions with a constant ionic strength reduces the margin of error between measurements. The HI-4008 cupric solid state ISE can measure from 1µM (0.065 mg/L) to 0.1M (6,355 mg/L).
