Pressure Reducer (optional with Extension „Diffusion Measurement“)
The CO Diffusion measurement is possible with the Diffustik
variant resp. by extending the PFTstik variant with the Add-on
CO Diffusion. A suitable pressure reducer for the Diffusion gas
bottle is required for safe application.
If you are planning the extension with Diffusion measurement,
please note:
Danger to life.
Reason: Poisoning by carbon monoxide (CO) during
prolonged exposure. Therefore:
•
Arrange the pressure reducer so that it is easily
accessible to enable the gas supply to be
quickly interrupted in the event of leakage!
Reason: damage to the CO Analyzer
because of excessive working pressure on the
demand valve. Therefore:
•
Only use a pressure reducer that complies with
the specifications defined by the manufacturer
and provides a fixed outlet pressure of 5
bar!
A suitable pressure reducer has been approved by the
manufacturer and is recommended for use. You can receive
this from your authorised specialist retail partner.

Accessories / Optional Expansions"
Depending on the regulations in the country of use, similar
pressure reducers may be considered. The inspection and
maintenance intervals specified in the operating instructions of
the pressure reducer used must be observed.
For a complete explanation of the diffusion measurement with
the Diffustik variant resp. when the "CO Diffusion" option is
added to the PFTstik variant, please refer to the separate IFU
Add-on CO Diffusion.
