This equipment was widely used in relative gravity measurement in the early days, such as CNPC's underground oil and gas exploration, Academia Sinica's whole Taiwan gravity measurement (distributed at the existing triangle points and benchmarks) and the gravity measurement plan of the military joint logistics survey team. Later, it was gradually adopted by digital However, there are still academic units using the same type of equipment for measurement and teaching purposes.

The gravimeter uses Hooke's law to convert the elongation value of the metal zero-length spring (Zero-Length Spring) into the acceleration of gravity. Because only the relative gravity difference can be obtained by energy, it is also called relative gravimeter.
