It stands out on account of its robust design,
guaranteeing a long life.
2. Intended use
The testo smoke pump is used to determine the
smoke number in oil burners.
3. Basic
safety information
Measuring correctly:
The testo smoke pump should be heated to
room temperature prior to use.
Check the sampling probe and connection
hose for soot deposits after every 10 measu-
rements and clean these and the other parts
of the flue gas pump regularly (See 5.1

with care.
Never use force.
4. Operation
4.1 Taking flue gas sample
The burner should be left burning for at least 5
minutes before taking a sample!
If the plunger is moving sluggishly, regrea-
se smoke pump (See 5.2 Regreasing
smoke pump)!
3 10 complete intake strokes should be carried
out: the pump plunger is pulled back to the
limit within 3 seconds.
- 1.63+/-0.07dm³ flue gas is taken in by the
filter paper, corresponding to stipulations.
4 Release knurled screw by turning it to the left
and remove filter paper strip.
- A black spot remains on the filter strip.
At least 3 samples must be taken to determine
the smoke number of a system! The smoke
number of the system is then calculated (See 4.2
Determining the smoke number).
1 Place filter paper strip in
the pump head slot and
clamp in position by tur-
ning the knurled screw to
the right.
2 Place the probe through
the opening in the flue
gas pipe and position in
the centre of the flue gas
flow.
