PM10 and PM2.5 Impactors of sampler based on designs standardized by US EPA
Two part cabinet ensures that temperature of PM 2.5 filter remains close to ambient temperature
Diaphragm Pump with a low noise
Lower sampling rate of 1m3/hr reduces filter choking even in areas having high FPM levels
Critical Orifice maintains constant sampling rate of 1 m3/hour
Sampler can run continuously 28 hrs monitoring
Low power consumption
Low weight essay to transport in field
Can be measured PM10 or PM2.5 at a time
Weight: Approx 25 Kg.
Owing to its modular design, APM 154 can be easily paired with a gaseous sampling attachment (for monitoring SO2, NOx, NH3, Ozone etc.) as gaseous sampling requires only a few LPM of air flow. This is possible through an attachable subsidiary unit LES 411. Kindly refer to respective brochures of LES 411
Size Selective inlets: Omni-directional air inlet with PM 10 separation through an impactor followed by PM 2.5 separation through a WINS Impactor
Flow Rate: Constant sampling rate of 1 m3/hr unaffected by voltage fluctuation and filter choking maintained by critical orifice system
Sampling Time Record: 0 to 9999.99 hrs. recorded on a Time Totalizer
Vacuum Pump: Diaphragm Pump
Power requirement: Nominal 220 V, Single Phase, 50Hz AC mains supply. For proper operation and safety, a good earth connection is mandatory
Automatic Sampling: 24 hrs programmable timer to automatically shut off the system after a pre-Control set time interval.
Sample Volume: Dry Gas meter records the total air volume sampled
