Air Pollution Monitoring Instruments

Product Details:

Features:

• 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
• Filter: Filter holder designed to accept any standard 47 mm diameter filter media
• Warranty: One year
