Изобретение относится к области испытательной техники и позволяет повысить точность контроля герметичности изделий космической техники в вакуумной камере. Заполняют изделие контрольным газом до заданного давления и одновременно подают в камеру тарированный поток контрольного газа, замеряют концентрацию контрольного газа в камере от тарированного потока и от изделия, прекращают подачи в камеру тарированного потока, замеряют концентрацию контрольного газа в камере от изделия, удаляют контрольный газ из изделия, замеряют остаточную концентрацию контрольного газа в камере и по степени уменьшения концентраций контрольного газа от изделия с учетом степени уменьшения концентрации контрольного газа от тарированного потока определяют величину негерметичности изделия.The invention relates to the field of testing equipment and can improve the accuracy of the control of the tightness of space technology products in a vacuum chamber. Fill the product with control gas to a predetermined pressure and simultaneously feed a calibrated control gas flow into the chamber, measure the concentration of control gas in the chamber from the calibrated flow and from the product, stop supplying calibrated flow to the chamber, measure the concentration of control gas in the chamber from the product, remove the control gas from products, measure the residual concentration of control gas in the chamber and the degree of decrease in the concentration of control gas from the product, taking into account the degree of decrease in the concentration of control th gas flow is determined from the calibrated leak value products.
