APM 550M

Simultaneous sampling of PM10 and PM2.5 Particulates. Two part cabinet ensures that PM2.5 filter remains close to ambient air temperature at all times. Low sampling rate of 1m3/hr reduced filter choking even in areas of high PM concentration Critical Orifice maintains constant flow rate. Oil free pump requires very little maintenance. Induction motor driven pump is immune to voltage fluctuation.

Particle Size	Omni-directional air inlet with PM10 separation through an impactor followed by PM2.5 separation through a WINS impactor. two separate streams for separation of PM2.5 and PM 10 Particles of dust are collected on two different filter papers .
Sampling Rate	Constant sampling rate of 1 m3/hr, unaffected by voltage fluctuation maintained by critical orifice system in each stream.
Filter Media	Filter holders designed to accept any standard 47 mm diameter filter media.
Sample Volume	Dry Gas Meter Records The Total Air Volume Sampled.
Power Requirement	Single phase AC 220 volts, 50 Hertz supply. Sampler unaffected by +/- 10% fluctuation in supply voltage
Warranty	One year
Sampling Time	Time Totalizer records the period of operation.
