Abstract

A device for testing a sample via a gas stream that includes an opening, a generator for generating a gas stream in the device along at least one flow path, at least one pressure sensor, and a mass flowmeter configured to measure the mass flow rate of the gas stream along each flow path. The flow path including an exhaust path terminating at the opening, and the gas stream generator configured to exhaust a leakage gas along the exhaust path. The pressure sensor includes an exhaust pressure sensor configured to measure a pressure of the leakage gas along the exhaust path, and the mass flowmeter is configured to measure a parameter representing the mass flow rate of the leakage gas along the exhaust path. A calculation device determines the size of a leak hole, based on a measurement of the parameter representing the mass flow rate along the exhaust path.
