A triple beam balance is an instrument used to measure mass very precisely. It consists of three beams, each of which is provided with a single reading scale that measures different increments of weight. The three beams are:
- The middle beam, which is the largest and reads in 100 gram increments.
- The far beam, which is of medium size and reads in 10 gram increments.
- The front beam, which is the smallest and can read from 0 to 10 grams.
The triple beam balance is primarily used to measure mass directly from objects, find mass by difference for liquids, and measure out substances. To measure the mass of an object, it is placed on the pan, which is on the left side of the balance. The user then adjusts the weights on the three beams until the balance is in equilibrium, and the mass of the object is read from the positions of the weights on the beams.
