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.

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.

  • Overview

    Our GenTwo PMA1000 V2.4 is designed for continuous measurement of oxygen concentration in gas mixtures. The paramagnetic oxygen measuring cells used are characterized by excellent linearity as well as high long-term stability and are largely cross-sensitivity-free due to the measuring method used.
    Through software parameterization and the installation of available options, each analyzer can be easily adapted to your application-specific requirements.  

  • Applications

    The GenTwo PMA1000 V2.4 can be used in a wide range of applications in non-hazardous environments. Typical applications include combustion control, process optimization, inertization monitoring, fermentation processes.
