This tester is a lightweight ergonomically designed tester. This pH and ORP tester is designed to float making it ideal for taking ORP measurements virtually anywhere. With this tester it is possible to monitor both pH and ORP at the same time. This tester is commonly used to monitor pH and ORP for many applications including swimming, food sanitization, plating wastewater treatment, and cooling tower water treatment.
Similar to a pH measurement that quantifies the how acidic or alkaline solutions are, ORP (Oxidation Potential) measurements quantify the overall state of a solution as having the ability to oxidize or reduce a chemical species. Oxidizing and reducing reagents are used to participate in chemical reactions known as a redox reaction.
An ORP meter must be chemically inert; it cannot be oxidized or reduced itself. It must also have the proper surface characteristics to promote rapid electron exchange, a property known as high exchange current density. Two noble metals have proven to work well for this purpose: pure platinum and pure gold are both used in the construction of ORP sensors.
