Aerosol Inlet
The aerosol inlet is at the bottom of the instrument.
The impactor is used to remove larger particles (> 0.7 microns), which would alter the measurements.
The impactor must always be
fi
tted before starting any measurement, either directly to the instrument or to
the end of the sampling extension set.
If the aerosol sampling point is far away from the testo DiSCmini inlet, please use the supplied extension
set.
The impactor is screwed into the testo DiSCmini housing. The „grit pot“ at the bottom of the impactor
must be unscrewed to remove the accumulated dust.
Impactor maintenance
It is recommended to clean the impactor every 8 hours of operation to avoid possible
clogging.
For this purpose please remove the impactor from the testo DiSCmini and disassemble
it by unscrewing its main body and grit pot. Clean the 6 lateral ori
fi
cies of the main body
using a thin steel pin or drill. The cylindrical surface of the grit pot can be cleaned using
ethanol or isopropyl and a soft paper wipe.
