Inert gas connection
NOTICE
Damage/Destruction of the device
The effects of uncontrolled gas flow (e.g. process gas) could distort the measurement or even damage
the device.
X Only use helium, nitrogen or argon as the inert gas at the intended connection. The pressure may
not exceed a maximum of 0.5 bar.
When measuring high power densities (CO2 > 15 – 30 MW/cm²; NIR > 8 – 10MW/cm²), plasma may be ignited
on the surface of the measuring tip. This could destroy the measuring tip.
Therefore, a protective gas connection is integrated in the device.
The connection is made via a 4 mm push fit connector.
