R718PA9 is a wireless communication device for detecting the ORP value of acid/ alkali/ salt solution.
ORP (oxidation-reduction potential) is an important indicator of water quality. Although it cannot independently reflect the quality of water, it can integrate other water quality indicators to reflect the ecological environment in the aquarium system.
