Will,

With a +/-2% level of accuracy, the measured value will be within 2% of
the value, not 4%.  Say you were measuring the F02 (OK, actually PP02) of
a mix with 10% O2.  Exactly 10% O2.  The reading would be somewhere
between 9.8% and 10.2% (+/-2% of the measured value.)  How presice do you
need your FO2 measurements?
