As per recent Air quality standard published by Govt. of India where measurement of PM 2.5 dusts has been made mandatory besides other parameters for defining the quality of ambient air. Ambient Air enters the APM 153 MINI sampler through an omni-directional 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 153 MINI are based on designs standardized by US-EPA and as such the system complies with international norms for PM 2.5 Samplers. The sampling rate is held constant at 1 m3/hr by a critical orifice.
