The invention relates to a device ( ) for determining the density of an electrolyte ( ). Said device ( ) comprises at least two immersion tubes ( ) provided with an open orifice ( ) and immerging at different depths in the electrolyte ( ), whereby said immersion tubes can be respectively filled with gas to a depth ( ) which is allocated thereto and each tube has a different gas depth (d) with respect to the other. A least one differential pressure sensor ( ) is used to define the difference in pressure inside the immersion tubes ( ). An electrode ( ) is respectively provided inside the immersion tubes ( ), whereby said electrode is connected to a voltage source ( ) in order to produce the required depth ( ) of gas so that said immersion tubes ( ) can be filled therewith upon contact with the electrolyte( ).
