Hanna HI4004 Calcium Half-Cell Ion-Selective Electrode (ISE)

The Hanna HI4004 is a liquid membrane, half-cell ion selective electrode (ISE) for the determination of calcium (Ca2+) in solution. The PVC membrane comprised with organic ion exchanger produces a potential change due to the calcium ion exchange between the organic polymer membrane and the sample. The internal sensing elements are housed within a durable epoxy body. The HI4004 is ideal for a variety of applications in the food and beverage industry and water analysis.

The HI4004 features a PVC membrane containing an organic ion exchanger that generates a stable potential through calcium ion exchange between the polymer membrane and the sample. This design ensures responsive and accurate measurements, even at low calcium concentrations, providing reliable results for quality control and research applications.

Housed within a durable epoxy body, the electrode offers excellent chemical resistance and mechanical strength, making it suitable for repeated use in both laboratory and field environments. Its half-cell design allows easy integration with a suitable reference electrode to simplify operation while maintaining accuracy.
