The HI4002 is a solid state, half-cell ion selective electrode (ISE) for the determination of bromide (Br–) in solution. The silver bromide sensing pellet produces a potential change due to the bromide ion exchange between the inorganic pellet membrane and the sample. The internal sensing elements are housed within a durable epoxy body.
The HI4002 is ideal for a variety of applications in the pharmaceutical industry, laboratories, drinking water and wastewater treatment, food and beverage production, and in printing processes.
The HI4002 bromide 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 silver bromide 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.
For the HI4002 to measure bromide accurately, it is important that the ionic strength of the standards and sample be adjusted to a high and constant value with the halide ionic strength adjuster (ISA) solution. The halide ISA ensures that the activity coefficient is constant so the concentration of free bromide ions can be measured. Measuring all solutions with a constant ionic strength reduces the margin of error between measurements. The HI4002 bromide solid state ISE can measure from 1µM (0.08 mg/L) to 1M (79, 910 mg/L).

Fixed Sensing Modules – Solid state half-cell ISEs are electrodes that detect free ions in a solution. The highly insoluble, compressed sensing pellet is attached to the HI4002 bromide half-cell by a fixed sensing module for ease of use.
Durable Epoxy Body – The probe body of the bromide half-cell ISE is composed of durable epoxy resin.
BNC Connection – The HI4002 has a universal BNC connector for easy connection to any benchtop meter with a female BNC probe input.
A solid state sensor electrode develops a voltage due to the ion exchange that occurs between the solution and the inorganic membrane. An equilibrium occurs due to the highly limited solubility of the membrane material in the sample. When the ionic strength of the solution is fixed by the addition of ISA, the voltage is proportional to the concentration of free ions in solution.
