“…Practical demonstrations of these approaches have been realised using analogues of conventional lead based sensors built with alternative anodes and 4M KOH electrolyte [23]. This presents some challenges since Cu is the only one of the chosen candidates readily available in a high surface area wire form.…”

Abstract:The requirement for the detection of oxygen in industrial safety applications has historically been met by electrochemical technologies based on the consumption of metal anodes. Products using this approach have been technically and commercially successful for more than three decades. However, a combination of new requirements is driving the development of alternative approaches offering fresh opportunities and challenges. This paper reviews some key aspects in the evolution of consumable anode products and highlights recent developments in alternative technologies aimed at meeting current and anticipated future needs in this important application.
