FH62 C14 Continuous Ambient Particulate Monitor
|
PRODUCT DESCRIPTION
The FH62 C14 Continuous Ambient Particulate Monitor by Thermo Fisher Scientific measures the mass concentration of suspended particulate matter (PM) (TSP, PM-10, PM-2.5, PM-C and PM-1) by use of beta attenuation and in addition radon gas activity measurement eliminates interference of natural airborne radioactivity.
The FH62 C14 particulate sample collection area 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.
This Ambient Particulate Monitor has user selectable reporting of mass concentration based on standard or actual flow rate and it is insensitive to vibration and diurnal temperatures (cycle of daily temperature changes).
