The APDA-371 automatically measures and records airborne particulate concentration levels (in milligrams or micrograms per cubic meter), using the industry-proven principle of beta ray attenuation.

Each hour, a small carbon-14 element emits a constant source of high-energy electrons (known as beta rays) through a spot of clean filter tape. These beta rays are detected and counted by a sensitive scintillation detector to determine a zero reading.

The APDA-371 Air Pollution Dust Analyser for Suspended Particulate Matter (SPM) ensures long term stability and self-diagnostic capabilities as well as efficient collection of fluorine resin tape. The measurement principle operates according to EU and EPA regulations and is also type approved by TUV.
