[0044] When using the hydrofluoric acid concentration meter main body 11;

[0045] First, the hydrofluoric acid concentration meter body 11 is placed on the measuring cup, and a pulling force is applied to the guide plate 26, so that the movable block 251 moves to one side of the movable frame 24, thereby driving the movable plate 25 to move synchronously in the fixed frame 23.
