The Fiber Monitor F-1K type is a measuring instrument that can sort out only fibrous particles such as asbestos from among the particles floating in the air and relatively calculate the fiber number concentration. Sample air is introduced into the inside from the air sampling port by the suction pump, passes through the detection unit, the sampling holder, the flow sensor, and is exhausted inside the housing. Fibers that match the count analysis value by phase-contrast microscopy can be sorted out and densitized. It can be used for monitoring, etc. for environmental management in asbestos treatment work. ● Data can be saved by logging measurement. ● An alarm notifies you when the set concentration is exceeded. (It can also be connected to an alarm device, etc.) ●It is possible to connect to a PC for constant monitoring. ●The backup filter can also be used for counting analysis. ●Displays fibrous particle concentration (f/L) in real time.
