A concentric tube vacuum gauge for measuring reduced pressures, characterized essentially by the fact that it consists of two vertical concentric tubes of which the exterior is closed at the top and at the bottom and only has a square fitting near its upper end for fixing from a vacuum rubber tube to the circuit to be controlled and the inner tube is graduated and its upper part is blind and it is attached to the outer tube and its inner part is finished in a conical shape, which is used to cushion the mercury blow, avoiding any possible breakage when said lower end is open and located a short distance from the bottom of the outer tube.
