Introduction
The PMX should be regularly cleaned to prevent dust accumulation in the event a potentially flammable dust (e.g. coal dust) is measured at high levels. The frequency of cleaning will vary depending on the levels being measured.
This procedure should be carried out in a fume hood or location with adequate ventilation (e.g. outdoors) to prevent inhaling respirable dust.

-
Remove the PM inlet from the PMX sensor head by pulling the inlet out of the sensor head.

Blow low pressure compressed air through the PMX sensor head to remove any accumulated dust. Flow for ~10 seconds should be sufficient.
-
-
-
Turn off the compressed air and remove the compressed air tubing from the PMX inlet barb.
