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.

With replaceable PTFE tube, for Ex zones 1 und 2

The electrically heated, self-regulating M&C sample lines 4/.../Ex are used in gas analysis systems for the transport of sample gas from the sample point to the gas conditioning system. They prevent measurement faults in the lower temperature ranges from +5 °C to +100 °C and protect the system against freeze. However, temperature monitoring of the total heated line is not possible due to the function as parallel heater band.
