Palas - Fidas® 100 氣溶膠粒徑譜儀


Fidas® 100 monitors are specifically designed for workplace exposure assessments and indoor air quality measurements and provide continuous and simultaneous measurements of PM1, PM2.5, respirable fractions (PM4), thoracic fractions (PM10), inhalable fractions (TSP), the particle number, and (upon request) the particle size distribution in 32 size classes per decade within the particle size range of 0.18 – 18 μm.*

The Fidas® 100 uses the recognized measurement technology of optical light scattering and is equipped with a white LED light source with highly stable output and long lifetime. The system is also equipped with a filter holder for the insertion of an absolute filter (47 or 50 mm in diameter). This enables the user to perform on-site gravimetric correlation or subsequent analysis of the composition of the aerosol.

The Fidas® 100 can be connected to an isokinetic sampling probe that measures emissions in exhaust air ducts.

The volume flow is 5 L/min.

The Fidas® 100 is additionally equipped with sensors for measuring environmental conditions, such as temperature, atmospheric pressure, and relative humidity.

Palas® offers remote maintenance and online data access for the device at www.palas.de/user.

(*) Other fractions can be implemented upon request. The size range can also be changed to 0.4 – 40 μm or 2 – 100 μm.
