In some aspects, the scale may include a housing supported by the base, the housing cooperating with the base to cover at least a portion of the measuring mechanism, and a connecting assembly operable to removably connect the housing to the base. In some aspects, the scale may include a resistance device coupled to at least one of the indicator and the measuring mechanism and operable to resist oscillation of the indicator at least one of during a measurement and after a measurement. In some aspects, the scale may include a cylinder supported by the housing, and a piston connected to the platform for movement with the platform, the piston engaging the cylinder to provide a piston and cylinder assembly, the assembly being operable to resist movement of the platform at least one of during a measurement and after a measurement.
