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
The lower sampling rate of 1m3/hr reduces filter choking even in areas having high FPM levels
Critical Orifice maintains a constant sampling rate of 1 m3/hour
The sampler can run continuously 28 hrs monitoring
Low power consumption
Low weight essay to transport in the field
Can be measured PM10 or PM2.5 at a time
Calibration Certificate for each instrument shall be provided with instruments
Compact and portable.
Weight: Approx 25 Kg.
APM 154 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
Filter: Filter holder designed to accept any standard 47 mm diameter filter media
