Barometric adjustment of the operating altitude of O₂ analyzers without pressure compensation

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.

Result: 22,9378 [vol%] need to be set to measure at the planned altitude without barometric error.*

*Air with standard pressure 1013 mbar = 20.93 vol% O₂

Pressure drop and delay time

Enter your values in fields 1 to 3.

2

3

Result: 3,39 Delay time approx. in [s]*

* Single change of gas, for 90 % response time approx. 3 changes of sample volume are required.

Calculation of the pressureless 100 % H₂O saturation

Enter the required H₂O dew point (°C).
The calculation only provides sufficiently accurate values in the temperature range between -20 °C and +90 °C.

The electrically heated, plug-in M&C sample lines series 3-N/M/H EX are used in gas analysis systems to avoid a distortion of measuring values and they also serve as anti-freeze protection during the transport of sample gas from the sample point to the gas conditioning system or directly to the heated analyzer (above dew point).
