QAL1 Dust sensor Dr. Födsch PFM20 certified
Continuous, certified QAL1 dust sensor, triboelectric monitoring of dust emissions
The PFM 20 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 QAL1 dust sensor is a Plug-And-Play device and easy to maintain.
The clamp connection also enables quick installation, and this assembly is also easy to disassemble for maintenance.
The robust design ensures a long lifespan > 10 – 15 years.
