Abstract

1. A method of examining the filling gas of insulating glass panes or the like having at least two individual panes and a gas-filled space therebetween, the concentration of at least one dense gas or the like in such space being ascertained by measurement and evaluation of the speed of propagation in such space of a signal parameter impressed on one of the panes, the sought-for gas concentration being calculated from such measurement and evaluation, characterised in that the signal parameter is a sound signal and the sound speed is found from the thickness of the space and the average resonant frequency therein in tuning through a frequency interval of standing waves which are formed.
