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!
Key Features:

  • Dual Channel enables measurement of PM-10 & PM2.5 Simultaneously
  • PM-10 Confirms to 40 CFR, Part 50 Appendix J of USEPA
  • PM-2.5 Confirms to 40 CFR, Part 50 Appendix L of USEPA
  • Micorprocessor based precision flow control for each channel
  • Data Logging of all parameters for each channel
  • Data Retrieval by USB and RS-232 ports

Extremely portable with foldable tripod stand and carry case
