FIELD: analytical chemistry.
SUBSTANCE: invention relates to control leaks and can be used, for example, to obtain quantitative characteristics of leakage of products, adjust and determine the sensitivity of leak detection equipment. Essence: the control leak contains sealed impermeable enclosure (1), filled with test gas, with hermetically sealed permeable element (3); pressure sensor (4) of test gas in housing (1), electronic device (5) reflecting on display (8) at the current time the digital value of the test gas flow through permeable element (3); electronic timer (6) and temperature sensor (7) communicated with electronic device (5). At the same time, the value of the measured internal volume of the leak cavity and the ratio is stored in the memory of electronic device (5) allowing automatically determine the flow of test gas.
EFFECT: technical result: increasing the accuracy of determining the flow of test gas from the control leak.
