The correct statement is: A triple beam balance is used to measure the mass of an object, and a spring scale is used to measure the weight of an object.

A triple beam balance measures the mass of an object regardless of the local gravitational field, while a spring scale measures weight, which is the gravitational force acting on an object and varies based on location (e.g., Earth vs. the Moon).
