An external fine filter must always be used at the gas inlet of the analyser. Depending on the
composition of the sample gas, it may be necessary to use a sample conditioning system.
Without precautions, the analyser is only suitable for measuring of non-hazardous gases or
gasmixtures in non-hazardous areas.

DC , 500mA, 15W
Response time for 90% FSD < 3 seconds at 60 Nl/hr air
Accuracy after calibration deviation ± 1% of 2-100% span, ± 2% of 1% span
Reproducibility deviation < 1% of span
Influence of ambient temperature no influence up to 50 °C
Influence of barometric- or
process pressure no influence within the range of 0,6 up to 1,6bar abs. with integrated pressure compensation
Influence of sample gas flow variation in gas flow between 0-60 Nl/hr air will cause a difference of < 0,1 vol.% O

Sample gas inlet pressure 0,01 up to 0,6 bar g, (PMA 100 requires positive pressure for adequate flow rate, no pump inside)
Sample gas outlet pressure recommendation: discharge freely into atmosphere; however max. 0,6 to 1,6 bar abs.
Flow rate of sample gas 25-60 Nl/hr air
Temperature of sample gas -10 °C up to +50 °C dry gas
