摘要：

A new procedure to measure liquid densities is presented. Assuming a hydrostatic equilibrium and ideal behaviour of the air closed in a tube connected to a manometer, the method allows us to establish a linear relation between the closed air pressure difference with respect to the atmosphere and the vertical penetration depth of liquid in the tube. In applying the procedure to water, density values are obtained at several temperatures.
