APM 550 MFC Respirable Dust Sampler

Listing ID #3320777

Ambient air enters the APM 550 MFC sampler through an omnidirectional inlet designed to provide a clear aerodynamic cut-point for particles larger than 10 microns. The air stream then passes through a WINS Impactor that retains the fraction between PM10 and PM2.5. The PM10 and PM2.5 impactors used in the APM 550 MFC are based on designs standardized by USEPA and as such the system complies with international norms for PM2.5 Samplers.
The sampling rate is held constant at 1 m3hr by a mass flow controller. An ambient air temperature sensor and barometric pressure sensor have been provided to automatically compensate for temperature and pressure while reporting flow rate in volumetric flow units. The APM 550MFC has an in-built data logger that records air temperature, filter temperature, flow rate and also totalizes and records the volume of air sampled. A PC based software is provided to download the data for audit.
features:
PM 10 and PM 2.5 Impactors of sampler based on designs standardized by US EPA.
Flow Control based on Mass Flow measurements to remove errors due to pressure, temperature changes (of both ambient air and filter).
Auto shut off if flow rate drops significantly below 1 m3hr.
Microcontroller based datalogger records Air Temp., Filter Temp. and Flow rate.
