, Part No.: 02A9000
Output signals 0-1V DC non-isolated, load > 100 KΩ, for the range of 100 vol.%, and
0-20mA or 4-20mA* for the chosen range, non-isolated, max. load 300Ω
Response time for 90% FSD < 3 seconds at 60 Nl/hr air
Accuracy after calibration deviation: analogue = ± 1% of span / digital = ± 0,1 vol.% O
2
Reproducibility deviation: analogue = < 1% of span / digital = ± 0,1 vol.% O

Influence of ambient temperature no influence up to 45 °C
Influence of barometric pressure The oxygen reading varies in direct proportion to changes of the barometric pressure.
Influence of sample gas flow variation in gas flow between 0-60 Nl/hr air will cause a difference of < 0,1 vol.% O
2
Sample gas inlet pressure 0,01 up to 1 bar g, (PMA 20 required admission pressure for competent flow rate, no pump inside)
Sample gas outlet pressure outlet of analyser must discharge freely into atmosphere
Flow rate of sample gas max. 60 Nl/hr air, adjustable with needle valve on the flowmeter 7-70 Nl/hr
Temperature of sample gas -10 °C up to +40 °C dry gas

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.
