CERTA 1000 FINE DUST MEASUREMENT FEATURES • Continuous real-time measurements of PM values simultaneously • Adjustable time resolution from one minute • Minimal maintenance activities • Easy to operate • Intuitive and easy handling with long durability and reliable functionality • LED light source with high stability • No consumables • Reduces operating costs • No radioactive material. APPLICATIONS The CERTA 1000 is a fine dust measurement system for regulatory ambient air quality measurements in a broad range of monitoring applications. The CERTA 1000 provides continuous and simultaneous measurements of PM 1 , PM 2.5 , PM 4 , PM 10 , TSP, as well as particle number concentration in the one instrument. APPROVALS PM 2.5 and PM 10 complies with the following: • EN 12341 • EN 14907 • EN 15267-1 • EN 15267-2 • Environmental monitoring networks (eg: mine sites and road tunnels) • Immission • Long term studies • Source apportionment • Propagation and distribution studies (volcano, bush fire, dust, cloud) • Emission source classification • Exhaust air monitoring • Emission measurement. OPERATION The CERTA 1000 systems use approved measurement technology of optical light scattering of single particles and are equipped with an LED light source with a stable output. In addition, the systems provide a filter holder for the insertion of an absolute filter (ø 47 or 50 mm). This enables a subsequent chemical analysis of the aerosol composition. The sampling system with a drying section (Intelligent Aerosol Drying System – IADS) prevents errors due to moisture ingress. An additional weather station offers reliable measurement values of ambient temperature, air pressure and relative humidity. The aerosol sensor is an optical aerosol spectrometer which uses the principle of Lorenz-Mie scattered light analysis of single particles. A white light source is used to measure the particles as they move through the measurement volume. The white light source allows a precise calibration curve to be created.
