Fidas 200, Fidas 200 E, and Fidas 200 S models are currently the only optical single particle measuring devices that are type approved for simultaneous monitoring of PM10 and PM2.5 acco?rding to standards VDI 4202-1, VDI 4203-3, EN 12341, EN 14907, EN 16450, EU Equivalence Guide GDE, certified in compliance with standards EN 15267-1 and -2 and UK (Defra Approval) in compliance with "MCERTS Performance Standards for CAMS" & "MCERTS for UK Particulate Matter".  The certificate of product conformity according to EN 15267 issued by TUV Rheinland and the German Federal Environmental Agency. The sampling system is equipped with a Sigma-2 sampling head according to VDI 2119-4 for representative sampling even under strong wind conditions, and a drying line that prevents condensation from causing measurement errors. An intelligent Aerosol Drying System IADS is controlled based on ambient air temperature, pressure, and relative humidity. An optional weather station can provide wind velocity, wind direction, and precipitation data, and an external 47mm dia filter holder is integrated, which allows external chemical analysis of the aerosol composition.
