Quality in detail SETUP & PRINCIPLE OF OPERATION Figure 1 shows the setup of the Fidas ® continuous ambient air quality monitoring system. Weather Station UMTS Antenna Heating Fan Sigma-2 Sampling Head IADS (drying system) Aerosol Sensor Absolute Filter Control Unit GPS Antenna Air Conditioned IP65-Protective Housing It consists of a Sigma-2 sampling head, which allows representative measurements in case of strong winds. An Intelligent Aerosol Drying System (IADS) avoids that the particle size measurement is affected by moisture, by using a dynamically regulated drying system with regard to relative humidity and ambient temperature. The aerosol sensor is an optical aerosol spectrometer, which determines the particle size and number by a scattered light analysis according to Lorenz Mie. The particles move separately through an optically differentiated measurement volume, homogeneously illuminated with white light. Each particle generates a scattered light impulse, detected at an angle of 85° to 95° degrees. The number concentration is deducted from the number of scattered light impulses. The intensity of the scattered light is a measure for the particle size diameter. Fig. 1 Setup of the Fidas ® 200 S fine dust measurement system The lower detection limit was reduced to 180 nm by using optimised optics, higher light density and improved signal analysis (logarithmic analog digital converter). In this way, smaller particles, measured roadside in high concentration, can be reproduced better (figure 1). The better the classification precision and the resolution capacity, the more accurate the particle size distribution can be defined.

Very efficient. Competitive pricing. The reminders, I’m so busy in my job that it’s so great to have a reminder to do something. It really helps me.
I’m very happy.
