Measuring range
|
Selectable for 0 to 3, 0 to 10, 0 to 30, and 0 to 100 vol.% O2, linear. (Zero suppression measuring range 99 to 100 vol.% O2 standard, also available ranges 97/90/70 to 100 % for S version)
|
|
Response time for 90 % FSD
|
< 3 seconds at 60 Nl/hr air
|
|
Accuracy after calibration
|
Analogue = ±1 % of span
Digital = ±0.1 vol.% O2 error of precision
|
|
Reproducibility
|
Analogue = <1 % of span
Digital = ±0.1 vol.% O2 error
|
|
Influence of ambient temperature
|
Zero point ±0.02 vol.% O2 / °C;
Sensitivity ±0.1 vol.% O2 / °C
|
|
Influence of barometric pressure
|
The oxygen reading varies in direct proportion to changes of the barometric pressure
|
|
Influence of sample gas flow
|
Variation of gas flow between 0 to 60 Nl/hr air will cause a difference of <0.1 vol.% O2
|
|
Sample gas inlet pressure
|
0.01 up to 1 bar g, (PMA 10 required admission pressure for competent flow rate, no pump inside) option: PMA 10 with internal pump, capacity 0.9 Nl/min. without pressure
|
|
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 to 70 Nl/hr
|
|
Temperature of sample gas
|
-10 to +40 °C, dry gas
|
|
Ambient temperature
|
-10 to +55 °C
