ORP Meters

10 products
Measure the cleanliness of water and its ability to break down contaminants with ORP meters from Grainger. Their sensors work by measuring the dissolved oxygen. More contaminants in the water result in less dissolved oxygen and therefore a lower ORP level. A higher ORP level indicates more ability of water to destroy foreign contaminants such as microbes, or carbon based contaminants.
