APM 460 DXNL

APM 460 DXNL is one of the most advanced PM10 samplers being manufactured in India. It is based on CSIR NEERI technology and is the only PM 10 sampler in India that  conforms to BIS 5182 (Part 23): 2006

Special features:

  • Automatic Flow Controller with electronic feedback for constant sampling rate throughout the sampling period.
  • Brushless regenerative blower with very little noise.
  • Heavy duty Induction motor fitted in blower requires no maintenance.
  • Blower immune to voltage fluctuations thus eliminating need of voltage stabilizer.
  • Electromagnetic interference (EMI) to TVs is totally eliminated.A

Automatic flow controller and auto shut off

In all previous models of particulate samplers in use in the country, the sampling rate varies with dust loading on the filter and fluctuates with changes in the mains voltage. The APM 460 DXNL uses an electronic flow controller to automatically maintain constant sampling rate through the filter/cyclone assembly. The size fractionating cyclone of the APM 460 DXNL thus operates close to its designed separation velocity resulting in a sharper cut-off for particulates larger than 10 microns. When the dust load on filter becomes excessive and exceeds the capacity of the blower the electronic circuits provided in the flow controller automatically shut down the machine.

Owing to its modular design, APM 460 DXNL 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 APM 411 or the more modern APM 411 TE. Kindly refer to respective brochures of APM 411 and APM 411TE for details

  • Flow Rate: Free flow (with flow stabilization disabled) > 1.3 m3 /min. 1.0 m3 /min with Filter Paper installed and Flow Controller enabled
  • Flow Rate Control: The system will automatically maintain the flow rate constant and compensate for dust load deposited on the filter. When the dust load increases beyond the capacity of the blower the flow rate will begin to decrease and the system will automatically be shutdown if the flow rate tends to drop below 0.85 m3 /min
  • Particle Size: Particles of 10 microns & below collected on Filter Paper holder. SPM bigger than 10 microns collected in a separate sampling bottle under the cyclone
  • Sampling Time: 28 hours (maximum)
  • Sampling Time Record: 0 to 9999.99 hrs. recorded on a Time Totalizer
  • Power requirement: Nominal 220 V, Single Phase, 50Hz AC mains supply. For proper operation and safety a good earth connection is mandatory
  • Size & Weight: 400 x 300 x 650mm., 60Kg
  • Automatic Sampling: 24 hrs programmable timer to automatically shut off the system after pre-Control set time interval.
  • Warranty: One year
