Test gases – Magnos206
Test gas for zero point calibration and single
-point
-point calibration
-free process gas
Process gas with a known O

concentration
suppressed measuring range
Zero point calibration: pure nitrogen or hydrogen-free
operating gas
Single-point calibration: 100 Vol.-% O

or test gas
with O

concentration in an existing measuring
Magnos206 with substitute gas calibration
Oxygen-free process gas or substitute gas (O

)
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.
