Fibrous Aerosol Monitors
With a fibrous aerosol monitor you can detect and count airborne fiberts that match a user specified size range.
MIE 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 prepare your rental as far in advance as possible to arrange the calibration required by your application.
