The presentation, authored by Julia Lange focuses on particle and flow measurements. It begins by outlining the agenda, which is divided into two main sections: particle measurements and flow measurements. The particle measurement section covers topics such as particle counters, coincidence, dilution systems, particle deposition, and isokinetic sampling. The presentation explains how particle measurement is used for purposes like cleanroom classification and filter efficiency testing. The second section of the presentation discusses flow measurements, including velocities, Laser Doppler Anemometry, volume flows, pressures, and turbulence intensity. It also addresses measurement uncertainty, differentiating it from measurement error. Overall, the presentation provides a detailed overview of various techniques and principles used to measure particles and fluid flow
