Sales, Rentals 1-614-846-1900 USA The portable MIE model FM-7400 Fibrous Aerosol Monitor is designed for continious air sampling and to detect (in real time) the presence of airborne fibers and to automatically count those fibers meeting user-selected fiber size criteria. The FM-7400 detects fibers by aligning the fibers in an oscillating electric field, illuminating the fibers with a polarized helium neon laser operating at 632.8 nm and detecting the resulting pulses of light with a photomultiplier. The characteristic frequency, phase and shape of the pulses enable discrimination between the fibers of interest and particles. The instrument is designed for a flow rate of 2 l/min. Sampling times of 1, 10 and 30 min and 1, 4 and 8 h can be programmed. The fibers taken into account are those with diameters lying between 0.2 and 20 m. A fiber length threshold facility allows values of 3, 5, 10 and 20 m to be chosen, the 5 m threshold being retained for this study. For correct operation, the relative humidity of the air must be between 30 and 90%. The measuring range extends from 10 4 to 25 fibers/ml. Please call 1-614-846-1900 for further details.
