The APM 550 system is a manual method for sampling fine particles (PM2.5 fraction) and is based on impactor designs standardized by USEPA for ambient air quality monitoring. Ambient air enters the APM 550 series samplers system through an omnidirectional inlet designed to provide a clean aerodynamic cut-point for particles greater than 10 microns.

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 PM 10 and PM 2.5.

The PM 10 and PM 2.5 impactors used in the APM 550 MINI are based on designs standardized by USEPA and as such the system complies with international norms for PM 2.5 Samplers. The sampling rate is held constant at 16.7 LPM by a critical orifice. It is lighter, more compact, can be carried in a car trunk, and is ideal for field use.

We are the proficient manufacturer of APM 550 ELAmbient Air Sampler that is easy to use. Provided with microprocessor based controller, it helps maintaining the constant air sampling rate. Also, the micro-controller based data logger records …

The Envirotech APM 550 is a portable particulate sampler designed to measure fine particulate matter (PM2.5) in ambient air. 2. It uses size-selective inlets and impactors based on EPA standards to separate PM10 and PM2.5 fractions from the air sample.

To purchase APM-550/APM-550 II spares or accessories, please contact the company via their website or visit an authorised retailer.

Ambient air enters the APM 550 system through an omni-directional inlet designed to provide a clean aero dynamic cut point for particles greater than 10 micros. Particles in the air stream finer than 10 microns proceed to a second impactor that has an aero-dynamic cut point at 2.5 microns.
