In life, fine dust is everywhere. We live in a fine dust environment all our lives. According to the American Cancer Society and Harvard University, for every 10μg/m³ increase in the average daily concentration of PM2.5, the death rate from heart and lung diseases increases by 6% and the death rate from lung cancer increases by 8%. Professor Christian Schulz from University Hospital Regensburg also described the impact of fine dust on human health in his health tips: inhalation of fine dust can irritate the mucous membranes, cause local inflammation of the respiratory organs, and increase the risk of onset of vascular disease. Therefore, more attentions is needed to monitor the concentration of fine dust correctly and reduce the exposure these harmful particles.
In recent years, worldwide stricter regulations were formulated to limit the emission of fine dust to improve the air quality and to protect the human health. In Europe, the maximum limit of PM10 particulate matter concentration is 50μg/m³, and this limit cannot be exceeded 35 times per year. China is also paying more and more attention to fine dust and its hazards, especially fine particulate matter PM2.5 which with a lower mass concentration. Studies have shown that the smaller the particle size and the longer the residence time in the atmosphere, the greater the probability of being inhaled by the human body. Due to the extremely small diameter of PM2.5, which is only 1/20 of human hair, it can directly penetrate human organs into the lungs, thereby endangering human health. According to China’s “Ambient Air Quality Standard” (GB 3095-2012), the limit of PM2.5 in residential areas, commercial and residential mixed areas, cultural areas, industrial areas and rural areas is less than 75μg/m³ in 24 hours.
Specially developed for monitoring air pollution
German particulate matter monitoring expert Palas® brings a new generation of particulate matter monitoring technology to the market. The Fidas®200 series of continuous automatic monitoring system for ambient air particulate matter is an aerosol spectrometer specially developed for monitoring air pollution. It can continuously analyze the fine dust particles in the ambient air and provide users with reliable data about the concentration of particulate matter through the single particle counting principle. The particle size range of Fidas®200 series equipment is 180 nm – 18 µm, and it can simultaneously monitor PM1, PM2.5, PM4, PM10, PMtot, particle number concentration Cn and particle size distribution.
The Fidas®200 series includes Fidas®200 and its two functionally identical variations: Fidas®200 E and Fidas®200 S. Fidas®200 E comes with a separate sensor for easier integration with existing sites. Fidas®200 S uses an all-weather case, which can be used for outdoor installation without air conditioning adjustment.

Principle of optical aerosol measurement
The Fidas® system uses the Lorenz‐Mie scattered light analysis of single particles. The better the classification precision and the resolution of a particle sizing instrument, the more accurately the particle size distribution can be determined. The Fidas® 200 light source allows for an unambiguous calibration curve, and thus very high particle size resolution and accuracy of classification. The Fidas® sensor is precisely optically delimited using the patented T-aperture technique, which allows particle sizing without border zone errors and so contributes to sizing accuracy.
One instrument, two parameters of particulate matter. Optimized design, higher accuracy and better cost-effectiveness.
Thanks to the single particle counting, the optical principle and the optimized algorithm of the Fidas® devices, PM2.5 and PM10 can be measured at the same time, no need to worry about data delay, no cutting needed.
Fidas® devices are equipped with a Sigma-2 sampling head that complies with the VDI 2119-4 standard, which allows representative sampling even under strong wind conditions. The intelligent aerosol drying system IADS adopts dynamic heating, which can adjust the heating power according to the real-time temperature and humidity, thereby effectively preventing the deviation of the measurement results due to the condensation effect under high humidity.
In addition, Fidas® devices also support online monitoring and remote access, users can check calibration at any time. Data availability exceeds 99%, the failure rate is extremely low. Thanks to the quality and technical advantages of the Fidas® fine dust monitoring system, energy consumption and operation & maintenance costs are drastically reduced.
Fulfilling multiple authorities and certifications at home and abroad
Fidas®200, Fidas®200 S and Fidas®200 E have all passed TÜV Rheinland’s reference method equivalence and applicability tests, and have been approved for environmental monitoring by official organizations and institutions. In addition, the Fidas®200 series have also passed the tests of DIN EN 12341 and DIN EN 14907, and certified in compliance with standards EN 15267-1 and -2.
Not long ago, Fidas®200 S and AQ Guard for outdoor monitoring were installed on the roof of an environmental monitoring center in China to monitor the concentration of particulate matter in the air in real time. Fidas®200 S can be used outdoors as a stand-alone device. It is small and easy to carry, and can be easily placed in the trunk of the car. It only takes 30-60 minutes to complete the installation and put it into use, easy to operate.

Widely used in many fields
The Fidas®200 series can be used in many fields, including environmental monitoring network, emission measurement, long-term research, emission source locating or spreading research (such as volcanic eruption, fire). At present, the measurement system has been successfully applied to public measurement networks in cities, coastal areas, mountainous areas, Arctic and desert areas.
Fidas®200 series devices can also be used in combination with SMPS nanoparticle sizing instrument U-Range 2000, which can measure the number and distribution of particles in the range from 7nm to 18μm.
