770-750A

Overview

DPM-7204 Monitor Kit includes monitor with battery, 37-mm opaque filter cassette, open-faced sampling adapter, GS-3 Cyclone, flow adapter, micro USB download cable, universal battery charger (110-240 V), zeroing accessory, USB with DustComm Pro Software and manual, and certificate of calibration, in a hard carry case. Requires calibration with equipment sold separately.

Details

The Environmental Devices Corp. DPM-7204 real-time monitor is a valuable tool for the OEHS professional. Immediately identify problem areas and tasks at highest risk for exposure to diesel particulate matter (DPM), implement controls, and measure the effectiveness of controls. You no longer need co-located real-time monitors and FRM filter cassettes ” DPM-7204 is two instruments in one with its built-in constant flow pump and sensor/filter configuration. The sensor mounts in the OSHA-defined breathing zone and is sandwiched between a 25 or 37-mm filter cassette and an interchangeable validated sampling inlet for accurate concurrent real-time measurement and gravimetric sampling of respirable, thoracic, or inhalable particulate size fractions. When used as part of a routine air monitoring program, the DPM-7204 can significantly reduce the number of gravimetric tests and laboratory analyses.
