The present invention provides apparatus and an associated method for testing containers for volume and leaks by employing a pump which provides rapid pressurized pulses simultaneously to a container being tested and a standard volume which may be a container. Acoustic impedance materials are interposed between the pump and the two containers to isolate the containers from each other. A differential pressure monitor is interposed between the two containers to provide output to electronic processing apparatus which may serve to either determine (a) solely if a leak exists or (b) in the alternative if no leak exists to determine whether the desired volume is present within the container.
