FIELD: testing equipment.
SUBSTANCE: group of inventions relates to means for testing devices for tightness and can be used to determine the integrity of a sealed container containing at least one gas. Essence: with the help of the element (220) to apply the mechanical force, the mechanical force is applied to the outer surface (201) of the container (200). Using a light source (210), which is a tuneable diode laser, a light signal is sent parallel to the portion of the outer surface (201) of the container (200). The sent light signal is detected using the detector (211). It is determined by the control unit whether the gas level has changed from the interior of the container (200) to the outside of the container.
EFFECT: possibility of prompt detection of even small leaks in a container without violating the integrity of the container itself.
