The HI-4004 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.
