A triple-beam balance is an instrument for measuring the mass of an object to a generally useful level of precision. It compares the object's mass to the triple beam balance's standardized calibrated mass through the manipulation of the balance's three masses (of 3 scales such as hundreds, tens and singles of grams), each along its own beam (three masses = three beams; thus, 'triple beam').

Mass is a very useful measurement for a variety of applications, including medicine and Biology (to measure how much mass an organism -- including a person -- has, and by measuring and comparing triple beam balance measurements over time, whether that organism is getting heavier/fatter or thinner/losing weight).
