Fibrous Aerosol Monitor Rentals

MIE Model FM-7400 FAM
Fibrous Aerosol Monitor

The FM-7400 is a continuous air sampler which detects and counts the presence of airborne fibers that match a user specified size range. The data can be continuously printed via the onboard printer. In order to obtain relevant data the FM-7400 must first be calibrated with the type of fiber to be detected. Please call us as far in advance as possible to arrange the calibration your application requires.
