ABPM 204M
Mobile Alpha Beta Particulate Monitor
The ABPM 204M forms part of the RAMSYS product
line.
Its small and light weight extendable sensor allows
this monitor to function locally next to the respiratory
tract of workers. A dual silicon detector performs the
gamma compensation. A processing
algorithm provides a dynamic compensation of radon
and thoron solid progenies.
Operating costs are minimised through unattended
operation, by the use of a continuous lter and the
on-line spectroscopy capability. All these features
make the ABPM 204M an ef cient diversi ed and
cost effective tool.
FEATURES
● Dynamic compensation of the radon and thoron solid
progenies
● Optimized beta measurement for environments with low
rate of radon
● On-line alpha spectrometry
● Up to 6 months lter cassette autonomy
● Optimized alpha measurement for low energies
