Accuracy
in standard conditions
in all conditions
The following specifications are valid for a dry gas at 22 ± 5°C and 1013 ± 40 hPa
(standard conditions).
• 0...15 % (± 0.2 vol % + 2 % of reading)
• 15... 25 % (no information on accuracy)
• ± (0.3 kPa + 4 % of reading)
Specification of accuracy in all conditions is valid for all specified ambient conditions (see
page
). Deviating from these, influences are specified in the table “Interfering gas and
vapour effects” and in section “Effects from water vapor partial pressure on gas readings”.
These technical specification can be found in the IRMA/ISA user guide chapter 2.
Breath detection
Adaptive threshold value, min. 1 vol% change in CO2 concentration
Respiration rate
0-150 /min. The respiration rate is displayed after three breaths and the average
value is updated after every breath.
