WARNING!IMPORTANT!
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 conditio-
ning system. Without precautions, the analyser is only suitable for measuring of non-
hazardous gases or gasmixtures in non-hazardous areas.

Output signals 0-10V 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 / 900Ω
Response time for 90% FSD < 3 seconds at 60 Nl/hr air
Accuracy after calibration deviation:
analogue signal output = ±1% of span at range 3-100% / digital indicator = ±0,1 vol.% O

= ±2% of span at range 1%
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

Sample gas inlet pressure 0,01 up to 1 bar g, (PMA 30 required admission pressure for competent flow rate, no pump inside)
Sample gas outlet pressure outlet of analyser must discharge freely into atmosphere;
option: process pressure compensation PD** in a range of 0,4 to 1,6 bar absolut Part No.: 03A9530
