HAZ-DUST DPM-7204

The Haz-Dust Real-Time Diesel Particulate Monitor Model DPM-7204 is a complete and personal portable system that allows true breathing zone measurements and comprehensive graph reporting. The product is designed for measuring diesel particulate matter for Industrial Hygiene and Environmental air investigations. The DPM-7204 is individually worn, and offers immediate determination and data storage of airborne diesel particulate concentrations. This is the only commercially available personal direct reading aerosol monitor, specifically designed and calibrated, for measuring occupational exposures of diesel particulate matter in the workplace with a flow compensated pump.

The inline 37mm filter cassette allows the user to concurrently collect filter samples for carbon analysis by NIOSH method 5040.

HAZ-DUST DPM-7204 Particulate Monitor with Cyclone
Specifications

The HAZ-DUST DPM-7204 optical particulate sensor operates on the principle of near-forward light scattering of infrared radiation. As the airborne particles enter the infrared beam, they scatter the light. The amount of light received by the photodetector is directly proportional to the aerosol concentration. Unique signal processing internally compensates for noise and drift. It immediately and continuously measures the concentration of airborne dust particles and displays the result in mg/m3.
