PAMS (PORTABLE AEROSOL MOBILITY SPECTROMETER)

Request Quote

PAMS is an electrical mobility size spectrometer designed for portable, mobile, or handheld aerosol sampling applications.
It provides the number-weighted diameter distribution of aerosols over the entire sub-micrometer range (10 to 863 nano meter) in one scan.

Electrical mobility size spectrometer designed for portable, mobile, or handheld aerosol sampling applications

Provides number-weighted diameter distribution of aerosols over the entire submicrometer range (10 to 863nm) in one scan

Uses a non-radioactive bipolar aerosol charger to allow easy access to sampling sites with tight safety regulations

Bipolar charger significantly reduces measurement uncertainty of larger particles in the submicrometer range

Can be used in two modes: Single diameter count mode: to get a total count within a narrow size range or Size distribution mode: to get an automated size distribution measurement over desired size range or size resolution

Stand-alone, battery-operated instrument; no external computer needed.

Weighs only 4.5 kg and measures 23 x 23 x 15 cm.
