(analytical chemistry) Gas analysis apparatus in which various gases are absorbed selectively (volumetric basis) by passing them through a series of preselected solvents.

kramarat is correct (as usual) and also electronic testing is much more accurate and will detect lower values.

That wasn't original on my part. I just googled it, as the OP should have done.

Oh, the fond memories.... An Orsat apparatus is an arrangment of lab glassware that allows you to raise and lower a bottle to move the sample through one or more reagents that selectively absorb the various gases of interest. After each step you you equalize the level and pressure of the bottle with those of the remaining sample in a finely graduated cylinder. If you Google "Orsat" you should be able to find some pictures.

My friend Tornado is so right. Please go and google FYRITE Instruments from Bacharach for this item.
