PFM 2 Ex Dust sensor Dr. Födsch
PFM 2 Ex Continuous, dust sensor, triboelectric monitoring of dust emissions
The PFM 2Ex is a very sensitive analyzer for continuous measurement of dust emissions. The dust measurement meets the highest international and European standards.
This simple measurement is very suitable for emission measurement at waste incineration plants and other combustion plants.
The PFM 02 Ex serves the permanent control of dustemissions. It can be applied as a filter monitoring deviceas well as configured as a dust measuring device in potentially explosive atmospheres.
The robust design ensures a long lifespan > 10 – 15 years.
