The invention relates to a device (2) for determining the density of an electrolyte (4). The device (2) comprises at least two immersion tubes (9, 10) which have an open tube mouth (52) and which are immersed at different depths in the electrolyte (4), each of which can be filled with gas up to an assigned gas depth (21, 22) and one to the other have preset gas depth difference (d). At least one differential pressure sensor (16) is used to determine the pressure difference in the immersion tubes (9, 10). An electrode (11, 19) is provided in each of the immersion tubes (9, 10), which is connected to a voltage source (5, 35) in order to fill the immersion tubes (9, 10) with gas upon contact with the electrolyte (4). down to the respective gas depth (21, 22). |
