The light weight ergonomically tester is designed to float making it ideal for taking readings virtually anywhere. It is possible to monitor both pH and ORP at the same time. This tester is commonly used to monitor pH and chlorine.

An ORP sensor 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.

Please note: This product requires the Hanna HI70300M Electrode Storage Solution. It must be stored in the solution prior to initial use.
