The probe is easily clogged if too much dust is contained in the sample gas such as in a utility
boiler or cement kiln. To get rid of the dust with compressed air, the piping from the air source is
connected only during cleaning. Blow back piping can be installed for dust cleaning as illustrated
in Section 4.3.1.
