摘要
Checking apparatus for checking operation of a densimeter for medium-voltage or high-voltage equipment having metal casing (4) that is filled with a dielectric gas under pressure; the apparatus comprises a closed chamber (8) suitable for being put into communication with an internal space (5) of the casing (4), and isolation means (10) for isolating the chamber (8) in gastight manner from the internal space (5), in which apparatus said closed chamber (8) has a volume that can be caused to vary, and in which apparatus the densimeter is suitable for detecting at least one pressure threshold in said chamber.
