Enter the planned operating altitude in the field. Set the analyzer to the calculated O2 vol% value at 1013 mbar (altitude = 0 m) in air to measure at the planned operating altitude without barometric error.
planned operating altitude above sea level in [m]
Result: 22,9378 [vol%] need to be set to measure at the planned altitude without barometric error.*
Enter your values in fields 1 to 3.
1 Hose/tube diameter in [mm]
2 Tube length in [m]
3 Flow rate in [Nl/h] Standard flow rate Nl/h Volume flow under following Defined conditions: Temperature = 273.15 K (0 °C) Pressure = 1,01325016 bar (760 mm HG) Air density = 1,294 kg/m³ (dry air)
Result: 3,39 Delay time approx. in [s]*
Enter the required H₂O dew point (°C). The calculation only provides sufficiently accurate values in the temperature range between -20 °C and +90 °C.
