BPM-200series
Atmospheric Dust Monitor
■ Product overview
Concentration index of respirable particles is an important
index for air quality. FPI combined years development
experience of environmental and safety testing
instrumentation with the highest demand of domestic and
international users', and used the β-ray technology, to
produce a new generation of BPM-200 series successfully
(atmospheric dust monitor). This monitor has the key “4h” BPM-200series atmospheric dust monitor
