Exhaust gas contains a lot of humidity, which can condense in the measuring device when the gas cools down. This could lead to problems with the measurement. Therefore, corresponding sensors are heated or the gas gets previously diluted. Exhaust gases from petrol and natural gas vehicles, however, contain a lot more humidity, which is why the device should only be used for diesel exhaust gases.
