Abstract
A cartridge (1) for mounting in a water circuit of an apparatus (3) comprises a chamber (6) having a first orifice (4) connected to a liquid reservoir, and a second orifice (5) through which the liquid exits. The chamber also contains a resin (8) for demineralizing the liquid, as well as a state-changing material indicating saturation of the said resin, the chamber having a transparent portion (7) permitting a user to verify a color change. The transparent portion (7) comprises two juxtaposed windows (9 and 10) and a separating partition (11) arranged between the first orifice (4) and the second orifice (5), one end of which terminates at the transparent portion (7) between the two windows (9 and 10) and the other free end of which separated from the peripheral wall delimits, for the liquid, a path of predetermined length so as to permit comparison between the two windows.
