Abstract
Test apparatus is provided for testing an electrical property of a fluid. The apparatus comprises an electrically conductive container (1) forming an outer electrode of a test cell for containing the fluid, an inner electrode (2) of the test cell, an inductive heating assembly (3) and a cooling means. The inner electrode (2) of the test cell is arranged, when mounted relative to the electrically conductive container (1), to project into, and remain electrically isolated from, the electrically conductive container (1). The inductive heating assembly (3) comprises an inductive heating coil (4), which surrounds the electrically conductive container (1), for heating the electrically conductive container (1) and the inner electrode (2). The cooling means comprises an air channel (9) to allow passage of air across a surface of the electrically conductive container (1), for cooling of the electrically conductive container (1).
