Spectro's model SLE -FPS105 is an advanced fine dust sampler, which can be used to determine the concentration of particular matter of size less than 2.5u in atmosphere. It has been specifically designed to comply with reference method for determination of PM2.5, when used without Imapactor (2.5u out stag), the system may be optionally used for particular matter less than 10u.

PMl0 and PM2.5 Impactors of sampler based on designs Standardized by US EPA
2 Same instrument can be used for PM10 and PM2.5 sampling
3 Lower constant sampling rate of 1m3/hr
4 Compact and portable
5 Sturdy construction for outdoor use
6 Easy setup and operation
Particle Size Omni directional air inlet with PM 10 separation through an impactor followed by PM 2.5 separation through a WINS impactor
Sampling Rate Constant sampling rate of 1m3/hr unaffected by voltage fluctuation and filter maintained by critical orifice system
Filter Media Filter holder designed to hold any standard 47mm dia filter
Sample Volume Dry Gas meter records the total air volume sampled
Power requirement Single phase AC 220 volts, 50 Hz
