FIELD: instrument engineering.
SUBSTANCE: invention may be used for testing unclosed volumes leaks in hollow products. Invention includes measuring tools of gas mixture parameters before volume to be tested, measuring unit of input gas mixture parameters in the tested volume and measuring unit of output gas mixture parameters linked with data processing and control unit. In addition, input and output parameters measuring units contain measuring tools of gas mixture pressure and temperature and concentration of, at least, one of gases. In addition, output parameters measuring unit contains time measuring tool for concentration change.
EFFECT: improvement of measurement accuracy and simultaneous reduction of labour costs for instrument operation.
