Do not use in the main duct!
Ensure that there are no leaks between the sampling
point and the device (escaping gas and atmospheric
oxygen can create an explosive mixture)!
Do not smoke or use naked flames during the
measurement!
Observe the rated pressure of the connections!
Do not exceed the measuring range!
No gas enters the device because an air cushion forms
between the sensor and the gas inlet. The measuring unit
is therefore not protected against explosions.
