Make sure you use something clean, like a washed coffee stirrer, rather than your hands. If the photometer doesn't work, try calibrating it first. Fluoride concentrations in water samples and appropriate aqueous standards are measured electrometrically using the ion-specific electrode. Testing kits are available online and at some home improvement stores. References. The potentiometric method involves direct measurement of the sample using an ion selective electrode (ISE) with a meter. The simplest way to test for fluoride in water is to test it with a strip fluoride testing kit.
