The potentiometric surface

WebbGround water in aquifers between layers of poorly permeable rock, such as clay or shale, may be confined under pressure. If such a confined aquifer is tapped by a well, water will rise above the top of the aquifer and may even flow from the well onto the land surface. Water confined in this way is said to be under artesian pressure, and the ... WebbOverview. The OPTISENS PH 8300 is a pH sensor for industrial or municipal wastewater, surface or process water applications. The glass sensor is equipped with a dirt-repellent PTFE diaphragm, making it particularly suitable for harsh applications. It is available with optional integrated Pt100 for temperature compensation.
