Scope

This standard specifies a chemically friendly optical method for the visual determination of oxygen in ambient air. This standard is applicable to the automatic measuring instrument with oxygen in ambient air. When the right range is 0 nmolymol to 500 nmolmol, the detection limit of this method under the reference state <298.15 K, 101.325 kPa) is 4hgm3, and the lower determination limit is 16 hg/nis. .
