representation of airborne particulate levels and exposures with data read out in milligrams per cubic meter (mg/m³). This dynamic capability is not possible with using only a gravimetric particulate sampler. The EPAM-7500 combines both the real-time and gravimetric technique, which allows the investigator more accuracy in defining and analyzing the nature and magnitude of potential health risk resulting from the inhalation of lung damaging particulates.
When the EPAM-7500 is deployed the sample air stream first passes by the light scattering sensor where particulate concentration is registered electronically, then the air stream is deposited directly onto a 47 mm gravimetric filter located directly behind the optical sensor as shown above. The 47 mm filter cassette is designed in accordance with the United States Environmental Protection Agency’s standards.
The EPAM-7500 offers a 24-hour rechargeable battery for portable flexibility and runs as a continuous monitor when used with the supplied AC power transformer. All is housed in a rugged watertight carrying case for ambient air monitoring. 50% smaller package than the EPAM-5000 with a new color graphical display.
The EPAM-7500 requires no special skills or tools and can be easily setup in minutes for measuring Particulate Matter PM-10, PM-2.5, PM-1.0 or Total Suspended Particulates (optional PUF foam sampling inserts allows for OSHA respirable and thoracic separations). All real time data is immediately stored in the instrument’s computer memory and can be viewed on the LCD display or downloaded to a PC using the provided graphical and statistical software package.
