Ideal for use in drinking water treatment, environmental monitoring, and plating baths, the HI-4010 is a solid state, half-cell Ion Selective Electrode (ISE) used for the detection of fluoride (F-) in a solution.
The lanthanum fluoride crystal membrane produces a change due to the fluoride ion exchange between the membrane and the sample. The internal sensing elements are encased in a durable epoxy body.
Hanna’s solid state half-cell ISEs are designed for use with the HI-5315 reference half-cell.
