Monitoring the oxygen concentration

With the ALTAIR, the oxygen concentration is monitored in the atmosphere. The
alarm setpoints can be set to enrichment (concentration > 20.8%) or depletion
(concentration < 20.8%).
Attention!
If an alarm is triggered while using the instrument as a monitor, leave
the area immediately.
Remaining on site under such circumstances can cause serious
damage to health or can even lead to death.
When a set value is reached, an alarm is triggered:

and the corresponding oxygen concentration.
In the event of extreme changes in the air pressure or the atmospheric
temperature, a false alarm can be triggered.
Therefore, calibrate the instrument under conditions of use.
