Water Quality Field Meters

Water quality field measurements should represent, as closely as possible, the ambient physical and chemical properties of the surface-water or groundwater system at the time of sampling. Properties such as temperature, DO concentration, and Eh must be measured directly (in-situ) in the water body. Other properties such as pH, conductivity, and turbidity may be measured either in-situ or from a sample withdrawn from the source, depending on the type of equipment selected for field measurements. These properties are measured at the field site.
