Safety rules
To safely operates the instrument, carefully follow
those indications.
1. Do not remove, for any reasons the enclosure
panels, without having turned o the instru-
ment and disconnected the power supply cable.
2. Always connect the instrument to a power
socket equipped with operational and ecient
grounding.
3. Do not operate the QB1 outdoor without hav-
ing provided protection from weather events
(rain, humidity etc).
4. Before starting any operation, nd a at and
stable accomodation for the QB1 with an ad-
equate sorrounding space for ventilation.
5. Operating temperature -10÷40°C
6. Max sampled gas temperature 45°C
7. Avoid contact and sampling of corrosive and
ammable compounds.
Precautions for humidity
Condense formation inside the sampler, reduces
the lifetime of some components, such as the pump
itself and dry gas meter as well.
Be sure the gases entering the QB1 are dry.
In case of presence of very wet/condensing gases
during the sampling, at the end of the operation,
allow the sampler to work with open air for at least
10 minutes.
The supply includes
QB1 is supplied with the following items:
♦QB1 sampler
♦Power cable
♦Sampling line quick connector
♦Hose barb for leak check
♦Operation quick guide
