Application and function
The dust measuring device PFM 02 Ex is a perfect device in order to
determine effectively damages at filtering precipitators on basis
of the triboelectric measuring principle. The device is simple in
construction and very user-friendly. The integrated micro-controller
allows numerous possibilities to use the PFM 02 Ex as well as a timely
monitoring of the dust emissions.
Special features
Target value calibration: Enter a known, averaged
dust content in operation state - The PFM 02 Ex determines automatically
appropriate calibration factors and shows the quantitative dust content
in mg/m³.
Selection from the dust list: The PFM 02 Ex offers
a selection of calibration graphs for chosen exhaust gases - Simply
chose the kind of facility from the dust list - The dust content is
given in mg/m³ without elaborate calibration.
