摘要： 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.

摘要： A device is provided for testing a sample via a gas stream, including: an opening; structure for generating a device gas stream along at least one flow path passing through the opening; at least one pressure sensor, each pressure sensor being arranged to measure a pressure of the gas stream along at least one flow path; and a mass flowmeter arranged to measure a parameter representative of the mass flow of the gas stream along the flow path. The device is arranged to quantify the presence of a gas of interest within a gas being analyzed and/or to determine the size of a leak hole from a measurement of the parameter representative of the mass flow. A method is also provided that is implemented by such a device. The method can be used to test the integrity of food packaging, and for detecting leaks or problems related to sealing containers.
