Application and function
The dust measuring device PFM 02 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 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 determines automatically
appropriate calibration factors and shows the quantitative dust content
in mg/m³.
Selection from the dust list: The PFM 02 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.
