ABSTRACT:
A density measuring apparatus includes a container for holding a fluid to be tested, a balance arm having a first end attached to the container, a fulcrum for supporting the balance arm, and a balance weight slidably disposed on the balance arm. The balance arm has an inverted channel shape cross-section defined by a top portion and first and second side portions depending downwardly from the top portion. First and second tabs extend downwardly from the first and second side portions and have first and second downward opening recesses disposed therein, respectively. A knife edge of the fulcrum engages the recesses of the tabs so that the balance arm is supported thereby. Approximately one-third of the length of the balance arm adjacent the container includes a longitudinally extending rib member located intermediate of the first and second side portions and depending downward from the top portion of the balance arm. A tab of the rib member extends downward therefrom and engages a notch in the knife edge of the fulcrum.
