Product information "HI4002 Bromide Half-Cell Ion Selective Electrode (ISE)"
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.
  • Solid state sensor
  • Detection from 0.08 to 79,910 mg/L Br-
  • Requires reference half-cell

Features at-a-glance

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.  


Theory of Operation

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.
