This tester is ideal for swimming pools and spas and can provide a valuable indication of water quality

Oxidation reduction is a process by which a molecule or ion loses or gains electrons. This occurs most readily in water treatment and in pool and spa maintenance where an oxidiser, such as chlorine, is added to the water to destroy contaminants. The higher the ORP value, the greater the sanitising power of your water.
