Abstract:
A metering system for measuring the concentration of a gas within a sealed insulating glass window having two spaced glass panes separated by an edge spacer, an edge seal and a cavity, from the outside of said window comprising:(a) an access port assembly having a connecting tube having one end within said cavity and a second end outside, a spacer block and a stopping means, wherein said spacer block is mounted adjacent said edge seal and said connecting tube is mounted through said spacer block, said edge seal and said edge spacer, thereby connecting said cavity to the outside; said stopping means securing said second end of said connecting tube; (b) a probing means for insertion through said access port assembly to said cavity for sensing said gas concentration; and (c) a measuring means for measuring, calibrating, scaling and displaying said gas concentration sensed by said probing means; wherein said access port assembly allows access into said cavity by said probing means from the outside, said measuring means attached to said probing means allowing for the measurement of said gas concentration.
