Balances having a reference mass and means for compensating for thermally induced errors such as shift of the zero-point and change of steepness in the characteristic of the balance. Bimetallic members are fastened to movable parts such as levers or other force transmitting members, or to the reference mass, and function as supports for masses acting as compensating masses. This allows for offsetting the two kinds of errors independently. Moreover, the bimetallic supports can be mounted on adjustable members, e.g. rotary disks or the like, to further adjust the desired amount of correction.
