Thermo Fisher Scientific is pleased to supply this continuous ambient
particulate monitor. We are committed to the manufacture of
instruments exhibiting high standards of quality, performance, and
workmanship. Thermo service personnel are available for assistance with
any questions or problems that may arise in the use of this instrument.
For more information on servicing, see the “ Servicing ” chapter.
The Model 5028 i uses the radiometric principle of beta attenuation
through a known area on a fibrous filter tape to continuously detect
the mass of deposited ambient particles. Additionally, the Model 5028 i
measures alpha particle emissions directly from the ambient aerosol
being sampled and excludes negative mass artifacts from the daughter
nuclides of radon gas decay to achieve a refined mass measurement.
