Particulates: Met One E-FRM-DC Ambient Air Sampler


The NEW and IMPROVED Met One Instruments E-FRM-DC sampler is a single-event filter sampler for the determination of daily PM2.5 or PM10 particulate concentrations in ambient air. 

The E-FRM-DC has evolved from the previous E-FRM model, now making it more versatile, with greater applications from permanent long-term sampling at a fixed site or as an audit sampler for frequent relocation in remote areas. The model E-FRM-DC is a single-event ambient air sampler designed to meet all US-EPA PM2.5 FRM specifications in accordance with 40 CFR Part 50 Appendix L.  Alternately, other sharp-cut cyclones can be installed for non-designated or indicative PM2.5 or PM1 sampling. 

Some countries do not require the full U.S. EPA FRM criteria for their PM2.5 sampling networks. These samplers may be supplied with a model BX-807 PM2.5 Sharp-Cut Cyclone instead of the VSCC cyclone or WINS Impactor.

The E-FRM-DC holds a single 47mm Teflon filter disc in a filter cassette. The cassette must be replaced by the operator for each sample. The flow rate is 16.7 L/Min. Flow data can be retrieved through any MODBUS compatible data acquisition system or can be easily downloaded and transported with your filter on a USB drive. 

The E-FRM-DC sampler folds down into its own stand for easy transportation and storage. 

Standard Accessories:

  • Main weatherproof instrument enclosure with quick deployment aluminum stand
  • BX-802 EPA Pattern PM10 Inlet
  • Pass-through adapter for PM10 sampling
