A portable test station is disclosed in a unitary package that integrates a typical Copper-copper sulfate reference electrode with test apparatus. The electrode is maintained in a state of equilibrium by way of immersion in a liquid environment which prevents the solution contained within the electrode from leaching out of the electrode's porous end. This feature enables extended periods of reliable service not otherwise possible. The liquid environment also serves as a conductive bridge between the electrode's porous end and the installation site's environment. Continuity is achieved by way of an adjustable porous ceramic plug located in the base of the apparatus, which may be manipulated by the user prior to installation, i.e. water is allowed to leech from the apparatus into the environment through the exposed surface area of the ceramic plug which may be increased or decreased to suit a particular installation's need.
