Note 1 : Negligible interference, effect included in the specification " Accuracy all conditions" above.
Note 2 : Negligible interference with N2O/O2concentrations correctly set, effect included in the specification " Accuracy all
conditions" above.
Note 3 : Interference at indicated gas level. For example, 50 vol% Helium typically decreases the CO2 readings by 6%. This
means that if measuring on a mixture contaning 5.0 vol% CO2and 50 vol% Helium, the actual measured CO2 concentration
will typically be (1-0.06) * 5.0 vol% = 4.7 vol% CO2.
Note 4 : According to the EN ISO 80601-2-55:2011 standard.
Note 5 : In addition to the EN ISO 80601-2-55:2011 standard.
