Question: what is the instrument used for experimental determination of the value of the universal gravitational constant G called?

Answer: the constant was first used in Isaac Newton gravitational law and was determined experimentally many years after that. It was calculated as a result of what is called the Cavendish Experiment.

This experiment used a torsion balance device to attract lead balls together, measuring the torque on a wire and equating it to the gravitational force between the balls. Then by a complex derivation, the value of G can be determined.
