Magnos206 with substitute gas calibration
Oxygen-free process gas or substitute gas (O
2
in N
2
)
Substitute gas, for example dried air
Dew point
The dew point of the test gases must be approximately equal to the dew point of the sample gas.
Note
The instructions for calibration must be observed, see Operating instruction.
