A base assembly for a beam balance instrument includes a box-like, open bottom base of lightweight sheet metal having an elongated slot in its upper wall, and a reinforcing strip or bar inlaid into the slot for rigidly supporting parts of the balance. The reinforcing strip is thicker and bulkier than the remainder of the base, and the fulcrum which pivotally supports the beam above the base is rigidly fastened on the strip, as is the sensor for detecting tilting of the beam in response to an applied force, and the bellows if the balance instrument is of the type used in measuring pressure variations.
