APM 550 MINI

Ambient Air enters the APM 550 MINI 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.

Special features:

• PM 10 and PM 2.5 Impactors of sampler based on designs standardized by US EPA
• Brushless, Oil-free, lightweight pump practically requires no maintenance
• Filter holder designed for any 47mm diameter filter media
• Critical Orifice maintains a constant sampling rate of 16.7 LPM
• Provision to attach gaseous sampler
• Compact cabinet design for easy portability
