Sample probe
Always use the correct sample probe. Probe 1 has a diameter of 10 mm and is used for exhausts with a diameter
smaller than 70 mm. Probe 2 has a diameter of 27 mm and used for exhausts with a diameter equal or larger than
70 mm.
Place the probe a far as possible in the exhaust. Take care the gas flow in probe is correct. Avoid sharps curves or
bending .
Figure 3. Placing the sample probe.
The temperature of the sample probe can rise up to 200 ºC during a smoke test. Always wear protection
gloves while you are touching the exhaust or sample probe.
During a zero calibration of the smoke meter, the sample probe must be removed from exhaust or the
engine must be switched off!
