Each EverFlo unit is measured in the factory with an Oxygen Analyzer that measures oxygen concentration with an
accuracy specification of +/- .1 %. When
using an Oxygen Analyzer with an accuracy specification of +/- 2 % to test
the Oxygen Concentration for an EverFlo Oxygen Concentrator, you may receive
inaccurate readings below the
acceptable pass criteria for the device. This 2% offset should be taken in to consideration when determining if the
EverFlo is
functioning properly. A more accurate Oxygen Analyzer may also be used for a more precise
measurement of the oxygen purity. As an example, a unit could be
measured in the factory with the +/- 1% Oxygen
Analyzer to measure 91.1%. If this same unit is then measured with a +/- 2% Oxygen Analyzer, the reading could
display a result of 89.1%. With the +/- 2% Oxygen Analyzer, it may inaccurately look like the unit falls below the 90-
95.5% specification, when in fact the unit is within specification.
