Abstract
A device for water quality measurement apparatus includes a plurality of multi-element arrays formed on a substrate, which are immersed in a solution for detecting electroactive elements or compounds present in such a solution. A wafer is located between first and second ‘O’ rings, with the first ‘O’ ring being disposed on a first side of the wafer and the second ‘O’ ring being disposed on a second side of the wafer, opposite to the first side. The first and second ‘O’ rings are arranged such that the wafer is exposed to substantially equal pressure on both sides.
