(see Fig. 2) and insert into the Y-connector (Fig. 1/2). The
arrow on the detector tube indicates the gas flow direction.
If the test is only being carried out to verify the presence of a
fault gas, the unused outlet of the Y-connector can be sealed
off using the sealing cap provided.
(4) Open the inlet valve (Fig. 1/5) and the gas withdrawal
valve (Fig. 1/4) so that the gases can be routed out of the gas
sampler through the detector tubes. The necessary pressure
for this inside the gas sampler must be > 0.5 bar. Observe the
rising oil level in the inspection window and close the inlet
valve (Fig. 1/5) and the gas withdrawal valve (Fig. 1/4) as soon
as the oil level is still approximately 2 cm from the top edge
of the inspection window.
(5) If a chemical reaction has taken place in the glass tubes,
then their contents will have discoloured. A discolouration
from green to reddish to rust brown must take place in the
detector tube for
hydrogen in order to confirm the presence
of hydrogen.
WARNING
Risk of explosion and risk of flammable and toxic gases!
In the event of an error, gases in the MESSKO® Gas sampler
may form an explosive gas mixture in connection with
air. Smoking or work involving sparks is prohibited in the
hazard area!
Avoid breathing in any gases escaping as they may be toxic.

insert them into the Y-connector. There is a risk of injury
due to cuts.
