A platform balance including a housing, a weighing platform vertically movable relative to said housing, and at least one force indicating lever pivotally movable in accordance with the mass to be weighed by said balance, characterized in that the force indicating lever is pivotally supported in said housing beneath said platform at the upper end of a vertical support member the lower end of which is pivotally connected with the bottom wall of the housing, said force indicating lever being operable by the platform via load lever linkage means connected between the opposed side walls of the housing. In the illustrated embodiment, a pair of symmetrical force indicating levers are connected for pivotal movement in opposite directions to increase the sensitivity of measurement. Adjustable weight means are provided for varying the operating range of the balance, and tangent error is compensated for by appropriate selection of the dimensions and location of the center of gravity of the vertical support member.
