Water is undoubtedly one of the most important natural resources, but the most important we have. The existence not only of the human being but of its activities depends closely on the capacity we have to access this resource and the quality of water that we can have for various activities, both daily and industrial. For this reason, measuring water quality and controlling pollution levels has become one of the priorities for different governmental entities and environmental institutions such as the United States Environmental Protection Agency (US EPA). The water quality monitors allow to monitor bodies of water of different types to know what their current state is in different parameters such as pH, OD, Conductivity, Turbidity among others. In this way, the quality of a body of water can be evaluated, as well as controlling whether it improves or worsens with the passage of time and the effects that human activity may have on it.
