, FH62 C14 continuous ambient particulate monitors measure the mass concentration of suspended particulate matter.
These continuous particulate monitors achieve this by using beta attenuation, with radon gas activity measurement eliminating the interference of natural airborne radioactivity.
The particulate sample collection area on these machines is located between both the C14 source and the proportional detector. While ambient particulate matter is being deposited onto a filter tape sample spot the dynamic filter loading is measured continuously by the attenuation of the C14 source beta rays and as a result a true continuous 'real-time' measurement of airborne particulate is provided.
FH62 C14 ambient particulate monitors also feature user selectable reporting of mass concentration based on standard or actual flow rate, and are insensitive to vibration and diurnal temperatures.
