EN 16450 approved fine dust aerosol spectrometer for simultaneous measurement of PM2.5 and PM10, featuring a separate sensor for existing roof glands
EN 16450 approved fine dust aerosol spectrometer for simultaneous measurement of PM2.5 and PM10 in weatherproof cabinet for outdoor installation
The Fidas® 200 System particulate matter monitor was explicitly developed for environmental regulatory monitoring. It is the market leader for continuous and simultaneous monitoring of ambient PM2.5 and PM10 in European countries and countries close to Europe. At the same time, the Fidas® 200 system is the most service-friendly, continuously measuring device. The officially recognized possibility to validate the system on-site is unique.
The Fidas® 200 version is a 19" plug-in unit for air-conditioned monitoring stations (temperature range 5 - 40 °C). Variants are the Fidas® 200 E with remote sensor (for easier integration into stations with existing roof penetration) and the Fidas® 200 S designed for outdoor installation (with stainless steel weatherproof housing), whereby this does not require full air conditioning, but can only be operated with an auxiliary heater for indoor temperatures below 5°C.
All versions are available with different weather stations and sampling tubes of different lengths.
Fidas® 200, as well as its functionally identical variations Fidas® 200 E and Fidas® 200 S, are optical single particle measuring devices that are type approved for simultaneous monitoring of PM10 and PM2.5 according to standards VDI 4202-1, VDI 4203-3, EN 12341, EN 14907, EN 16450, and the EU Equivalence Guide GDE and certified in compliance with standards EN 15267-1 and -2. Type approval declaration of the Fidas® 200 was published first in the German Federal Gazette BAnz AT 02nd April 2015 B5 in chapter IV, notification 14. The product conformity certificate issued by TÜV Rheinland and the German Federal Environmental Agency and the measuring system test report for the version Fidas® 200 S compiled by TÜV Rheinland are published at www.qal1.eu .

Beyond that, the fine dust measurement devices Fidas® 200 as well as Fidas® 200 E and Fidas® 200 S are also type approved and certified in the UK (Defra Approval) in compliance with the requirements of "MCERTS Performance Standards for CAMS" and "MCERTS for UK Particulate Matter." The respective MCERTS/DEFRA Approval certificate, as well as the test report , are publicly available.

Operating principle
The Fidas® 200 fine dust monitor uses the recognized measuring technique of optical light scattering according to ISO 21501-1 on the single particle and is equipped with an LED light source of high light intensity, high light stability, and long service life. The instrument's calibration can be easily and quickly checked and, if necessary, adjusted at any time, even when installed, using a monodisperse test aerosol.
The sampling system of the Fidas® 200 operates with a volume flow of approx. 0.3 m3/h.
It is equipped with a Sigma-2 sampling head according to VDI 2119, which enables representative sampling even in strong winds, as well as a drying section, which demonstrably prevents falsification of the measurement due to condensation effects at high humidity.
The Fidas® 200 fine dust monitor offers a wide range of communication options and allows complete remote control and remote maintenance of the systems as well as data access online via palas.de. The supplied software offers a wide range of options for evaluation (including extensive statistics and mean value calculations) and for exporting measurement data.

Multiple separation curves can be applied simultaneously to the same size distribution data, which allows simultaneous calculation and output of, e.g., PM10 and PM2.5 and other mass fractions.
The drying section (Intelligent Aerosol Drying System - IADS) is controlled based on the outside temperature, air pressure, and relative humidity. A weather station supplies these measured values; wind speed, wind direction, and precipitation can also be measured on request. A filter holder for planar filters (ø 47 mm or ø 50 mm) is integrated into the sampling system, which enables, for example, subsequent chemical analysis of the aerosol composition.
