Dual Channel Ambient Dust Sampler

When it comes to innovation in Ambient Air Sampling technology, Instrumex has delivered yet again! The most common hassle faced by Consultants in order to comply with the CPCB norms for Ambient Air Sampling - was using two separate instruments for measurement of PM2.5 & PM10 Dust. Instrumex has found the solution to this problem - The Dual Channel Sampler for measurement of PM2.5 & PM10 dust concentrations in ambient air – Simultaneously!

The flow control module uses the proven technology used in Instrumex’s IPM-FDS 2.5/10µ Fine dust Sampler that has enjoyed over 400 installations across India and abroad. The two channels in IPM-FDS-2510 are individually controlled by separate flow control element but integrated into a single controller module. Thereby giving precise microprocessor based flow control for two channels. Both the channels individually comply with Federal Reference Method of USEPA as described in 40 CFR Part-50 Appendix L for determination of Particulate Matter. It also confirms with the CPCB guidelines for Measurement of Ambient Air Pollutants.

Features

  • Dual channel enables measurement of PM2.5 & PM10 Simultaneously
  • Confirms to USEPA & CPCB Guidelines
  • Options for PM2.5, PM10 and TSP Sampling
  • Precision flow control for each channel by Embedded Microprocessor
  • Extremely portable with Foldable tripod stands and carry case
  • Designed for outdoor use
  • In field data retrieval by USB and RS-232 ports
