Palas - Fidas® 100 氣溶膠粒徑譜儀

Palas -Fidas® 100氣溶膠粒徑譜儀

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

The Fidas® 100uses the recognized measurement technology of optical lightscattering and is equipped with a white LED light source withhighly stable output and long lifetime. The system is also equippedwith a filter holder for the insertion of an absolute filter (47 or50 mm in diameter). This enables the user to perform on-sitegravimetric correlation or subsequent analysis of the compositionof the aerosol.

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

The volume flow is 5 L/min.

The Fidas® 100is additionally equipped with sensors for measuring environmentalconditions, such as temperature, atmospheric pressure, and relativehumidity.

Palas® offersremote maintenance and online data access for the device atwww.palas.de/user.

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