Abstract
Two autoclave systems designed for use as part of a programme to develop better materials for use in desalination plants are described. One system utilises an external reference electrode and is suitable for electrochemical investigations in which a knowledge of the potential relative to the hydrogen scale is required. The second system utilises an arbitrary internal reference and is designed specifically for the measurement of corrosion rates. Provision is made for the control, not only of temperature, but also of flow velocity and oxygen concentration. The details of these systems, including problems encountered, are presented in an expanded form to facilitate the construction and operation of similar systems by other investigators. Specimen results obtained using both systems are given.
